Replace substring inside a list-CodePudding

I have a list of strings with a few unclean entries and I want to replace the unclean entries with clean entries

list = ['created_DATE', 'column1(case', 'timestamp', 'location(case']

I want to get a list that is like this

cleanList = ['created_DATE', 'column1', 'timestamp', 'location']

I tired the following:

str_match = [s for s in list if "(case" in s]     *#find the intersecting elements*
print (str_match)

new=[]
for k in str_match:
   a=k.replace("(case" , "")
   new.append(a)           *#make an list of the words without the substring*
print(new)

I am not sure how do I now replace the entries from the new list into the original list. Can someone please help. Thank you

If you want to remove all occurrences of "case(" from your list's elements, then you could write it like this:

list = ['created_DATE', 'column1(case', 'timestamp', 'location(case']
clean = []

for n in list:
    clean.append(n.replace("(case", ""))
    
print(clean)

You can either create a new list clean as told by @alani:

import re

myList = ['created_DATE', 'column1(case', 'timestamp', 'location(case']

clean = [re.sub("\(.*", "", s) for s in myList]

print(clean)

or iterate over elements of myList and update in place

for i in range(len(myList)):
  if "(case" in myList[i]:
    myList[i] = myList[i].replace("(case" , "")
print(myList)
