def kill_char(string, n): # n = position of which character you want to remove
    begin = string[:n]    # from beginning to n (n not included)
    end = string[n+1:]    # n+1 through end of string
    return begin + end
print kill_char("EXAMPLE", 3)  # "M" removed

我在这里某处见过。

这可能是最好的方法:

original = "EXAMPLE"
removed = original.replace("M", "")

不要担心转换字符之类的问题。大多数Python代码发生在更高的抽象级别上。

def kill_char(string, n): # n = position of which character you want to remove
    begin = string[:n]    # from beginning to n (n not included)
    end = string[n+1:]    # n+1 through end of string
    return begin + end
print kill_char("EXAMPLE", 3)  # "M" removed

我在这里某处见过。

另一种方法是用一个函数，

下面是通过调用函数从字符串中删除所有元音的方法

def disemvowel(s):
    return s.translate(None, "aeiouAEIOU")

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。

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','')
