advanture_of_code's Issues

Functional

If you want to use function, better can put the 00000 as one argument, then easier to reuse

map cannot be called twice, why?

losing map, map cannto be used 2nd time, why?

a = range(1,10)
mymap = map(lambda x: x*x, a)
list1 = list(mymap)
list2 = list(mymap)

print(f'my list1 is {list1}')
print(f'my list2 is {list2}')

question for q2

你为什么更喜欢在一开始用tuple来存储数据？
boxspecint=list(map(int, boxspec))这句的map是个没见过的函数。
calnum=reduce((lambda x,y:x+y), results) 为什么用这种方式求和，看不懂reduce的好处

why the final df is empty

import pandas as pd

lst1 = ['(22,99)@(214395,133691)@Angle_Angle.jpg',
 '(100,103)@(126184,138057)@PadDefect2_PadDefect2600.jpg',
 '(100,156)@(126221,192559)@PadDefect2_PadDefect2600.jpg']

df = pd.DataFrame(columns = ['X', 'Y', 'DC'])

for f in lst1:
    [a, b] = f.split('@')[0::2]
    x, y = a.replace(r'(', '').replace(r')', '').split(',')
    #print([int(x), int(y), b.split('.')[0]])
    temp_pd = pd.DataFrame([[int(x), int(y), b.split('.')[0]]], columns = ['X', 'Y', 'DC'])
    print(temp_pd)
    df.append(temp_pd)
    
df
