Question

So from this string:

‘name[id]’

I need this:

‘id’

I used str.split (‘[]’), but it didn’t work. Does it only take a single delimiter?

Answer 1

Use a regular expression:

import re  s = 'name[id]' re.find(r'\[(.*?)\]', s).group(1) # = 'id' 

str.split() takes a string on which to split input. For instance:

'i,split,on commas'.split(',') # = ['i', 'split', 'on commas'] 

The re module also allows you to split by regular expression, which can be very useful, and I think is what you meant to do.

import re s = 'name[id]'  # split by either a '[' or a ']' re.split('\[|\]', s) # = ['name', 'id', '']
