Remove char at specific index - python

Question

I have a string that has two \"0\" (str) in it and I want to remove only the \"0\" (str) at index 4

I have tried calling .replace but obviously that removes all \"0\

Answer 1

rem = lambda x, unwanted : ''.join([ c for i, c in enumerate(x) if i != unwanted])
rem('1230004', 4)
'123004'

Answer 2

Try this code:

s = input() 
a = int(input()) 
b = s.replace(s[a],'')
print(b)
