如何在Python字符串中删除逗号

Question

如何从Python字符串中删除逗号Foo, bar？我试过了'Foo, bar'.strip(','),但没办法.

Answer 1

你想要replace它,而不是strip它:

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

Answer 2

使用replace字符串的方法不是strip:

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

一个例子:

>>> s = 'Foo, bar'
>>> s.replace(',',' ')
'Foo  bar'
>>> s.replace(',','')
'Foo bar'
>>> s.strip(',') # clears the ','s at the start and end of the string which there are none
'Foo, bar'
>>> s.strip(',') == s
True

Answer 3

unicode('foo,bar').translate(dict([[ord(char), u''] for char in u',']))
