How do I remove a character once from a string [python]?

Question

Is there a better way than what I am doing?

word = "baab"
word = word[:word.find('a')]+word[word.find('a')+1:]
print word #bab

In[3]: "baab".replace('a', '', 1)
Out[3]: 'bab'

Will replace a only once with nothing, hence removing it.

You can use the string replace function with a maximum count:

s = s.replace('a','',1)

as in the following transcript:

>>> s = "baab"
>>> s = s.replace('a','',1)
>>> s
'bab'

From the documentation:

str.replace(old, new[, count])

Return a copy of the string with all occurrences of substring old replaced by new. If the optional argument count is given, only the first count occurrences are replaced.
