Python字符串 endwith() 方法

如果字符串以给定的后缀结尾， Python String endswith() 方法返回 True，否则返回 False。

Syntax:

str.endswith(suffix, start, end)

Parameters: 

• suffix: Suffix is nothing but a string that needs to be checked. 
• start: Starting position from where suffix is needed to be checked within the string. 
• end: Ending position + 1 from where suffix is needed to be checked within the string.

示例 1：没有 start 和 end 参数的 endswith() 方法的工作

Python

# Python code shows the working of
# .endswith() function
  
text = "geeks for geeks."
  
# returns False
result = text.endswith('for geeks')
print (result)
  
# returns True
result = text.endswith('geeks.')
print (result)
  
# returns True
result = text.endswith('for geeks.')
print (result)
  
# returns True
result = text.endswith('geeks for geeks.')
print (result)

输出：

False
True
True
True

示例 2：带有 start 和 end 参数的 endswith() 方法的工作

Python

# Python code shows the working of
# .endswith() function
  
text = "geeks for geeks."
  
# start parameter: 10
result = text.endswith('geeks.', 10)
print(result)
  
# Both start and end is provided
# start: 10, end: 16 - 1
# Returns False
result = text.endswith('geeks', 10, 16)
print result
  
# returns True
result = text.endswith('geeks', 10, 15)
print result

输出：
