从文本文件字符串中删除特定字符

Question

I have a text file with the following line in it: ('larry', 3, 100) I need to assign the three parts of it to different variables using a method close to what I have below. So far I can split it down, but I cannot remove the brackets and apostrophes from the result. I have tried other solutions on stackover for hours to no avail...

filecontent = filename.read().strip().split(',')

for i in filecontent:
    name = filecontent[0]
    weeks_worked = filecontent[1]
    weekly_payment = filecontent[2] 

print ("name:" + name)
print ("weeks worked:" + weeks_worked)
print ("weekly payment:" + weekly_payment)

gives the result:

name:('larry'

weeks worked:3

weekly payment:100)

How do I make it show just:

name:larry

weeks worked:3

weekly payment:100

Answer 1

You'll want to use ast.literal_eval here, which will convert the string to a tuple:

import ast
filecontent = ast.literal_eval(filename.read().strip())

You also don't need a for-loop, you can also just do:

name, weeks_worked, weekly_payment = filecontent

Answer 2

You can use regex either after or before split.

    filecontent = filename.read().strip().split(',')

    for i in filecontent:
        name = re.sub(r'\(|\)|\'','',filecontent[0])
        weeks_worked =  re.sub(r'\(|\)|\'','',filecontent[1])
        weekly_payment = re.sub(r'\(|\)|\'','',filecontent[1])

OR I would prefer doing this

   filecontent = re.sub(r'\(|\)|\'','',filename.read().strip()).split(',')

And then do your usual stuff.
