str.endswith(suffix[, start[, end]]) 检查字符串是否suffix来结尾的,是返回true,否返回false. Return True if the string ends with the specified suffix, otherwise return False. suffix can also be a tuple of suffixes to look for. With optional start, test beginning at that position. With optio...
4 Beginning with Python 1.6, many of these functions are implemented as 5 methods on the standard string object. They used to be implemented by 6 a built-in module called strop, but strop is now obsolete itself. 7 8 Public module variables: 9 10 whitespace -- a string containing all ...
In this tutorial, we will learn about the Python String join() method with the help of examples.
result = text.startswith(('programming','easy'),12,19) # prints Falseprint(result) Run Code Output True False False If you need to check if a string ends with the specified suffix, you can useendswith() method in Python. Also Read: ...
str.endswith(suffix[, start[, end]]) --> Bool(TrueorFalse)用于判断字符串是否以指定后缀结尾,如果以指定后缀结尾返回True,否则返回False。 可选参数"start"与"end"为检索字符串的开始与结束位置 1>>>str ="TestPython"2>>>sub ="test"3>>>print(str.endswith('on'))# 判断该字符串以指定后缀‘...
为了在Python中判断给定字符串的开头和结尾,可以使用方法str.startswith()和str.endswith() str.startswith(prefix[, start[, end]]) 顾名思义,str.startswith用于判断给定字符串是否以前缀中的给定字符开头 s = "This is a test string" s.startswith("Thi") # True s.startswith("thi") # False 注意...
