Python how to only remove the first duplicated character in a string-CodePudding

I have a string 'cbbcc',I want to remove 1 of the characters in each round, from left to right, and return the remaining character, like this:

first round:  bbcc
second round: cbcc
third round:  cbbc
Forth round:  cbbc

But if I use the following code:

    for i in s:
        old_s=s
        s=s.replace(i,'')
        print(s)
        s=old_s

The output will be:

bb
ccc
ccc
bb
bb

Is there anyway I can make the output like:

bbcc
cbcc
cbbc
cbbc

In real business the string can be very very long.

CodePudding user response：

Perhaps you could slice the string, instead of replacing:

for i in range(len(s)):
    print(f"{s[:i]}{s[i 1:]}")

Output:

ba
aa
ab

CodePudding user response：

try this

s = 'aba'

for i in range(len(s)):
    new_s = s.replace(s[i], "", 1)
    print(new_s)
