Any chance of writing an explanation of the 'with' method/function (?) that you use in the video please? I got a little lost there. (Complete-Python-3-Bootcamp/00-Python Object and Data Structure Basics/08-Files.ipynb)

#can i use this code??

def player_input():
value=input('make a choice:')
condition=True
while condition:
if value=='X':
print('you have choosen {}'.format(value))
return ('X','O')
break
elif value=='O':
print('you have choosen {}'.format(value))
return ('O','X')
break
else:
condition=False
while not condition:
value=input('please make a choice again between X or O:')
condition=True

When I first went on to Jupyter Notebook it worked fine, but after a few lessons of using it the code would not work at all and it would show: In[*]. No matter what code I put in it just wouldn't work. I tried restarting the Kernel, deleting other files, everything! I eventually went on to Jupyter lab but it did the exact same thing that Jupyter Notebook did. Can someone please help me out with this?

I like to confirm if i can download the video to enable me watch the video training without using my data

I am struggling tiwrite the code down it won't allow me to write anything

When attempting to open: 14-Advanced Python Objects and Data Structures/04-Advanced Dictionaries.ipynb I get an error that says: "Sorry, something went wrong. Reload?"

All other files have opened for me, thus far.

I am unable to write the code.How do I redirect it to Jupyter notebook?

Hi, everyone.
Can someone please explain to my what the expression "nums[i:i+2]" do in the find_33 problem.

The solution is like follows:
def has_33(nums):
for i in range(0, len(nums)-1):

    # nicer looking alternative in commented code
    #if nums[i] == 3 and nums[i+1] == 3:

    if nums[i:i+2] == [3,3]:
        return True  

return False

I had a question about the slide in the course that mentions the global function. The example was like this:

x = 50

def func(x):
print (f'X is {x}')
# local reassignment!
x = 200
print (f'I just locally changed x to {x}')

func(x)
--> X is 50
I just locally changed x to 200.

print(x)
--> 50

I totally get all of this. What happens next confuses me, when the global function is added.

x = 50

def func(x):
global x <------ shouldn't this be overwriting x as 200 everywhere?
print (f'X is {x}')
# local reassignment!
x = 200
print (f'I just locally changed x to {x}')

func(x)
--> X is 50 <------ so this should be 200? Why is it still 50?
I just locally changed x to 200.

print(x)
--> 200 <------- and this should also be 200?

Hope that's clear! Thank you so much!

Hello

I have been asking for assistance on my local kernel disconnecting for the past month. I am attempting to finish my certificate with the Udemy Python 3 course Zero to Hero. It seems when I run input functions ex:

def play_game():

  start_game = str(input("Ready..? Yes or No: ")).

A hourglass appears next to my Jupyter notebook. After I cannot run any code. The only solution I have found is to restart the kernel, but short thereafter if I run my input functions it occurs again. This is a very frustrating issue that has set me back a couple weeks from my anticipated end date for my Udemy course. I have no got any reliable feedback and would greatly appreciate some help with issue.

Thanks,

Thomas

Trying to do the functional practice exercise but it won't allow me to make any edits or changes in the coding?

import math

def is_prime2(num):
'''
Better method of checking for primes.
'''
if num % 2 == 0 and num > 2:
return False
for i in range(3, int(math.sqrt(num)) + 1, 2):
if num % i == 0:
return False
return True

is the program correct, because for ever number it just returns true

Hi Pierian-Data,

On this page:
https://github.com/Pierian-Data/Complete-Python-3-Bootcamp/blob/master/00-Python%20Object%20and%20Data%20Structure%20Basics/09-Objects%20and%20Data%20Structures%20Assessment%20Test.ipynb

You asked:
Can you sort a dictionary? Why or why not?

And in your keynote, you mentioned that the dictionary is unordered key-value pairs. I don't think that's true any more in CPython 3.6+ (as an implementation detail) and Python 3.7+ (as a language feature).

This is the mail found in python.org

https://mail.python.org/pipermail/python-dev/2017-December/151283.html

Though python still does not provide the sort method, we could still "sort" it as it retains insertion order.

sort_dict = lambda d: dict(sorted(d.items()))

The solution that has been provided for the question "Summer of 69" doesn't give the correct solution.

When it is tested with
summer_69([1, 3, 5]) => it is OK but
summer_69([6,1, 3, 5]) => it is not correct.

My solution is ;

def summer_69(arr):
total = 0
start = 0
end = 0
flag = False

for i in range(len(arr)):
    if arr[i] == 6:
        flag = True
        start = i

    if arr[i] == 9 and flag:
        end = i

    total += arr[i]

if start >= 0 and end >= 1:
    total = total - sum(arr[start:end+1])

return total

Hi, I encountered this issue when I try to pass in a list object in a function inside another function. I have a game_on() function with all the main code. There I had a pre-defined value(hand) func to calculate hand value comparing to 21. but when I try to pass in player_hand, this error keeps pop out but when I wrote it eslewhere. it is fine. Please see attached screenshot:

If I try to do the same at a new block, there will be no message as 'str' object is not callable. It would work as it should be.

Could you advise on the issue?

Thanks!

Write a Python function that checks whether a passed string is palindrome or not.

Note: A palindrome is word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run.

I have problem. When my string have more than 1 part "Nurses run", y take only first part "Nurses". I don't know why. Can someone help me?

def palindrom(string):
word = string.split(" ")
y = ""
for z in word:
y += z
if y.lower() == y.lower()[::-1]:
print(word)
print(y)
return f" True word = {y.lower()}, palindrom = {y.lower()[::-1]}"
else:
print(word)
print(y)
return f"False word = {y.lower()}, palindrom = {y.lower()[::-1]}"

Is paper_doll('Mississippi') this should be paper_doll('Missippi')?

Where should I write the answer?

Hi everyone
Can anyone help me to return a list when using **kwargs or *args

Please help me out:)

i get this error

Hello,

I was just wondering for the Functions and Methods homework assignment question 5 - multiply all the numbers in a list - are the square brackets used to turn 'numbers' into a list with an unknown number of variables?
e.g.

def multiply(numbers):
total = numbers[0] <----- I don't quite get this bit - why [0]?
for x in numbers:
total *=x
return total

Thanks so much for your help!

this is level 2 problems from function exercise
Given a list of ints, return True if the array contains a 3 next to a 3 somewhere.
sol:
def has_33(nums):
for x in range(0,len(nums)-1):
if nums[x:x+2] == [3,3]:
return True
else:
return False

here, we want to find array contains 3 next to 3.
in slicing we need to put nums[x:x+1]
I think we need to check next position so we need to use x:x+1
but we are using x:x+2
please help me understanding this
