Python string.endswith() is used to check the end of a string for specific text patterns e.g. domain name extensions and so on.
1. String endswith() method
A simple way to check the end a string is to use the String.endswith().
>>> url = 'https://howtodoinjava.com'
>>> url.endswith('.com')
True #Output
>>> url.endswith('.net')
false #Output
2. String endswith() with tuples
If you need to check against multiple choices, simply provide a tuple of strings to endswith().
>>> domains = ["example.io", "example.com", "example.net", "example.org"]
>>> [name for name in domains if name.endswith(('.com', '.org')) ]
['example.com', 'example.org'] #Output
>>> any( name.endswith('.net') for name in domains )
True #Output
3. String endswith() with list or set
To use endswith(), tuple is actually required as input. If you happen to have the choices specified in a list or set, just make sure you convert them using tuple() first.
For example:
>>> choices = ['.com', '.io', '.net'] >>> url = 'https://howtodoinjava.com' >>> url.endswith(choices) #ERROR !! TypeError: endswith first arg must be str, unicode, or tuple, not list >>> url.endswith( tuple(choices) ) #Correct True #Output
