Another method, without using split:
另一种方法，不使用拆分：
s = 'Zaptoit:685158:[email protected]'
s[s.find(':')+1:]
Ex:
前任：
>>> s = 'Zaptoit:685158:[email protected]'
>>> s[s.find(':')+1:]

As of Python 2.5 there is an even more direct solution. It degrades nicely if the separator is not found:
从 Python 2.5 开始，有一个更直接的解决方案。如果找不到分隔符，它会很好地降级：
>>> s = 'Zaptoit:685158:[email protected]'
>>> s.partition(':')
('Zaptoit', ':', '685158:[email protected]')
>>> s.partition(':')[2]
'685158:[email protected]'
>>> s.partition(';')
('Zaptoit:685158:[email protected]', '', '')

Output:

Use the method str.split() with the value of maxsplit argument as 1.
使用方法 str.split() 并将 maxsplit 参数的值设为 1。
mailID = 'Zaptoit:685158:[email protected]'
mailID.split(':', 1)[1]
Hope it helped.
