Python String Substring count() function Output: Find all indexes of substring There is no built-in function to get the list of all the indexes for the substring. However, we can easily define one using find() function. def find_all_indexes(input_str, substring): l2 = [] length = len...
When working with text data in Python, a team member was checking whether a string contains a particular substring. I suggested a few methods that Python provides to do this. Let me show you different methods tocheck if a Python string contains a substringusing some real-time examples. To c...

Return the number of non-overlapping occurrences of substring sub in the range [start, end]. Optional arguments start and end are interpreted as in slice notation. str.decode([encoding[, errors]]) 解码 Decodes the string using the codec registered for encoding. encoding defaults to the default...
In Python, a substring can be extracted by using slicing. Many times, programmers want to split data they have into different parts for some specific purpose. For example, if a developer has data as the full name of a user and he requires the only first name to use, then, in this cas...
The python str class has a __contains__() method that will check if a python string contains a substring. It will return true if it’s found and will return false if it’s not. You will notice that the method name is wrapped in two underscores. This prevents this method from being ...
