1. except is not properly indented
2. It is Exception , not Exceptions

Modified Code

Hey, guys. I want to join it, but how to start it. Anybody could tell me? Thanks for help.

I have a c++ code,there are two classes,that in the init function,they need the other class' object. also in one class,init function need itself object as a parameter.
how to deal with such situation in python.
many thanks!

Hi
I'm using Spyder 3.6 for Python on Windows 10, every time I try to open the editor, it takes nearly 4-6 mins of my time and sometimes even longer. The same happens if I open through Anaconda launcher. Is there anything that I could do to fix it,

thanks in advance

In check_file.py, the list filenames is changed on line 40 and line 47.
Thus, some items may skip the for loop (and does not get the existance check and read permission check), when you try to read such items on line 54, an error may be thrown.

For example, suppose there is non-readable file f1 and non-exist file f2 in current directory, and we execute the command python check_file.py f1 f2, we will see an error as shown in the picture.

sides_change parameter is passed to the function set_sides. Within the function set_sides, instead of using the sides_change variable directly, self.sides_change is used. It is resulting in an error.

Hi,I use python3 to test a model which need opencv(CV2),but I failed to install opencv on windows.
Therefore,I try to find a functions which belongs to numpy or PIL to replace it.
Here are partial codes of the program.

for rec_val, img,x,y in zip(reconstruction_vals, test_images, xs, ys):
rec_hid = (255. * (rec_val+1)/2.).astype(int)
rec_con = (255. * (img+1)/2.).astype(int)

                rec_con[y:y+64, x:x+64] = rec_hid
                cv2.imwrite( os.path.join(result_path, 'img_'+str(ii)+'.'+str(int(iters/100))+'.jpg'), rec_con)
                ii += 1
                if ii > 50: break

            if iters == 0:
                ii = 0
                for test_image in test_images_ori:
                    test_image = (255. * (test_image+1)/2.).astype(int)
                    test_image[32:32+64,32:32+64] = 0
                    cv2.imwrite( os.path.join(result_path, 'img_'+str(ii)+'.ori.jpg'), test_image)
                    ii += 1
                    if ii > 50: break

Hi ,
I was trying to copy a file into a A.jar (without extracting it) but it didn't work.
Suppose i have file copy.txt in D:\python\copy.txt and i want this file to be copied into my A.jar/org/here

for this I have written a code in python but what it is doing is , It is taking the contents of copy.txt and pasting the content to target dir-> A.jar/org/. It is not pasting the file instead it is pasting the content. I want the file to be copied with the content and if the file is already exist it will replace it in the target dir.
Please see my below code and suggest .

import zipfile, os

def show_jar_classes(jar_file):

zf = zipfile.ZipFile(jar_file, 'a')
try:
    #Code to write inside org folder in inside z.jar
    
    dir=input("please give the source file dir along with the file")# taking complete path frm user
    m='/'
    
    dir= dir.replace('\\',m) #formating the path by replacing '\' with '/'
    clas=os.path.basename(dir) #extracting the file name from the given path
    
    zf.write(dir, "org\\"+clas) #writing into A.jar/org/
finally:
    zf.close()

jar_file = 'D:/python/A.jar'
show_jar_classes(jar_file)

Extract to get A.jar.zip

I'm learning python, and after having done some lessons, it was suggested that I browse Github, find a python project, and just read some code to gain more experience. Your batch file rename script is the first one I looked at, and it appears to have an error.

You have the following code:

if old_ext == file_ext:

which means it will only "rename" to the same name, defeating the purpose of the entire script.

python study

I installed python from brew

brew install python

then installed pip

sudo easy_install pip

in Terminal

$ which easy_install
/usr/bin/easy_install

$ which python
/usr/bin/python

But then when I want to install any Python script I get this:

Here's an image of the problem:

I saw your files and they are not compatible with python 3. I will like to make them work with Python 3.5 too. Let me know if you want someone to work on it.

Shouldn't all the .py files all have shebangs?
For example:

!/usr/bin/python3

(Assuming the user is on Linux/Unix. If the user is on windows it will be read as a comment and no harm will be done.)

testing

it says,
ImportError no module named crypt:

page = ('.... facebook .....')
Link_start = (page.find('<a href'))
starting_quote = (page.find('"','Link_start'))
end_quote = (page.find('"','starting_quote+1'))
url = (page.find('stating quote+1','end quote'))
print (url)

As I saw, most of the scripts support only Python 2.x. There should be a support for python 3.X also.

It includes adding aliases for function names, such as raw_input() to input() , adding parantheses to print.

FYI, you can use enumerate() to simplify osinfo.py. Instead of this:

i=1
for item in profile:
print( '#',i,' ',item)
i=i+1;

... do this ...

for i, item in enumerate(profile, 1):
print( '#',i,' ',item)

This repo has a lot of great programs, it would be great if similar types of programs were organized into folders so it is easier to find them and would be better in the future for more programs to be added to this repo.

def readfile(filename):
with open(filename, 'r') as f: # Ensure file is correctly closed under all circumstances
line = f.read() # more convenient it should be file = f.read()
print(line) # print(file)

#Because it is reading whole file not a single line.It is just an enhancement.

I looked through your code and as a current student learning python I was asked to pick any code and see if I can correct any errors.

Well I would think adding an "else" statement to the main function would help in preventing the processing of empty password files by the users.

Your scripts are not PEP8 valids. However, there're a lot of others issues :

• way too much commentarys for not enough docstrings
• invalid files metadata format (cf http://stackoverflow.com/questions/1523427/what-is-the-common-header-format-of-python-files)
• some unclear things...

Should I contribute to fix them ?

OS : Windows 7
Python 2.7

total=0
temp =0
i=0;
j=1;
counter=0
MIN_val = 100
MAX_val = 0
file = open("C:/Users/Shrikanth/Desktop/Report.csv")
csv_reader = csv.reader(file)
next(csv_reader)

for all in csv_reader:
FileName, Channel, OrgSize, TransSize = all
if Channel == "TimesNow_LB":
total_redn= (float(OrgSize)- float(TransSize))/float(OrgSize) * 100
counter = counter + 1
MIN_val(float(total_redn))
MAX_val(float(total_redn))
AVG_val(float(total_redn))

print counter
def MIN_val(num):
global MIN_val
if MIN_val > num:
MIN_val = num
print MIN_val
def MAX_val(num):
global MAX_val
if MAX_val < num:
MAX_val=num
print MAX_val

So i'm getting ''MIN_val(float(total_redn))
TypeError: 'int' object is not callable'' error.
Why does it happen and what is the solution?

what should i do ?
thanks so much!

Please can you help solve this in Python and explain to me

mystery_int_1 = 7
mystery_int_2 = 2

You may modify the lines of code above, but don't move them! When you Submit your code, we'll change these lines to assign different values to the variables.

The variables below hold two integers, mystery_int_1 and
mystery_int_2. Complete this program below such that it
prints "Factors!" if either of the numbers is a factor of the other. If neither number is a factor of the other, do not print anything.

Hint: You can do this with just one conditional statement
by using the logical expressions (and, or, and not). You'll also use the modulus operator

Please help me with the Add your code here!

Have tried several means am just not getting it

hey,

really liked these codes. inspirational i must say... 💯 ..

Why don't you create a .txt file and put all dependencies for using any of the codes in this source, might be helpful for all.

temperature = -3.7
celsius = True

You may modify the lines of code above, but don't move them! When you Submit your code, we'll change these lines to assign different values to the variables.

Above are given two variables. temperature is a float that holds a temperature. celsius is a boolean that represents whether the temperature is in Celsius; if it's False, then the given temperature is actually in Fahrenheit.

Add some code below that prints "Freezing" if the values above represent a freezing temperature, and "Not freezing" if they don't.

In Celsius, freezing is less than or equal to 0 degrees. In Fahrenheit, freezing is less than or equal to 32 degrees.

Comment your code

For ex20.py
Comment "What is the program and what will it do"
