lstrip unexpected output: removes additional character

Question

lstrip removed additional character, please help me understand it why. Is it removing all the input characters from the beginning?

'http://twitter.com/c_renwick'.lstrip('http://twitter.com/')
>>>'_renwick'

Because `'c' in 'http://twitter.com/'`. Read the docs for `.lstrip` - `help(str.lstrip)`. It would probably be easier to implement this with `.rsplit` instead. — jonrsharpe, Jan 22 '18 at 13:31
@Chris_Rands in that case, yes, that'd work. But what if the relative URL is deeper? — Jean-François Fabre, Jan 22 '18 at 13:38
I mean: `http://twitter.com/c_renwick/something` how does `basename` manage with that? — Jean-François Fabre, Jan 22 '18 at 14:03

lstrip takes a list of characters to remove from the string. As c is in the list you provided, it gets removed

To achieve what you actually want, use replace:

'http://twitter.com/c_renwick'.replace('http://twitter.com/','')
