使用translate()方法:

>>> s = 'EXAMPLE'
>>> s.translate(None, 'M')
'EXAPLE'

下面是我切掉“M”的方法:

s = 'EXAMPLE'
s1 = s[:s.index('M')] + s[s.index('M')+1:]

如果你想删除/忽略字符串中的字符，例如，你有这个字符串，

“[11:L: 0]”

来自web API响应或类似的东西，比如CSV文件，假设你在使用请求

import requests
udid = 123456
url = 'http://webservices.yourserver.com/action/id-' + udid
s = requests.Session()
s.verify = False
resp = s.get(url, stream=True)
content = resp.content

循环并去除不需要的字符:

for line in resp.iter_lines():
  line = line.replace("[", "")
  line = line.replace("]", "")
  line = line.replace('"', "")

可选的分割，你将能够单独读取值:

listofvalues = line.split(':')

现在访问每个值更容易了:

print listofvalues[0]
print listofvalues[1]
print listofvalues[2]

这将打印

11 l 0

取代:取代特定的位置:

s = s[:pos] + s[(pos+1):]

替换一个特定的字符:

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

在Python 2中，可以使用UserString。MutableString以可变的方式来做:

>>> import UserString
>>> s = UserString.MutableString("EXAMPLE")
>>> type(s)
<class 'UserString.MutableString'>
>>> del s[3]    # Delete 'M'
>>> s = str(s)  # Turn it into an immutable value
>>> s
'EXAPLE'

MutableString在Python 3中被移除。

from random import randint


def shuffle_word(word):
    newWord=""
    for i in range(0,len(word)):
        pos=randint(0,len(word)-1)
        newWord += word[pos]
        word = word[:pos]+word[pos+1:]
    return newWord

word = "Sarajevo"
print(shuffle_word(word))
