那个莫名其妙的"which must be a string of length 256"就不用深究了,反正table就是由string.maketrans方法生成的,对于string.maketrans方法,这里有个更清晰的解释,如下: string.maketrans(intab, outtab) --> This method returns a translation table that maps each character in the intab string into the c...
可以用来去除字符的函数有: strip(), replace(), re.sub(),strip()去除首尾指定字符,不传参数为去除空格>>> s = '/n 123456 /n' >>> s.strip('/n') ' 123456 ' >>> s. #Python字符串中删除指定字符串在Python中,我们经常需要对字符串进行一些操作,比如删除指定的字符串。本文将介绍几种方法来删...
In addition,Python’s strings support the sequence type methods described in the Sequence Types — str, unicode, list, tuple, buffer, xrange section. To output formatted strings use template strings or the % operator described in the String Formatting Operations section. Also, see the re module ...

简单来说就是对字符串S移除deletechars包含的字符,然后保留下来的字符按照table里面的字符映射关系映射(比如a变成A)。 无deletechars的例子 #!/usr/bin/pythonfromstringimportmaketrans#Required to call maketrans function.intab="aeiou"outtab="12345"trantab=maketrans(intab, outtab) ...
The key to understanding this recipe lies in the definitions of the translate and maketrans functions in the string module. translate takes a string and replaces each character in it with the corresponding character in the translation table passed in as the second argument, deleting the characters...
