my_list=['A0_123','BD_SEI','SW_TH']

I need to replace the '_' to ' ' .

Expected output: my_list=['A0 123','BD SEI','SW TH'] Can some one help me?

CodePudding user response：

As pointed out by @python_user, you can iterate through every element in your list using a list comprehension and using replace():

new_list = [i.replace('_', ' ') for i in my_list]

Returns your expected output

['A0 123', 'BD SEI', 'SW TH']
