When it is required to fetch all the occurrences of a substring from a list of strings, a list comprehension and the ‘startswith’ method is used.
Example
Below is a demonstration of the same −
my_string = "Python learn code test fun amazing object oriented" sub_string = "object" print("The string is : " ) print(my_string) print("The sub-string is : " ) print(sub_string) my_result = [index for index in range(len(my_string)) if my_string.startswith(sub_string, index)] print("The resultant string is : ") print(my_result)
Output
The string is : Python learn code test fun amazing object oriented The sub-string is : object The resultant string is : [35]
Explanation
A string is defined and is displayed on the console.
A sub string is defined and is displayed on the console.
A list comprehension is used to iterate over the string and check if the string starts with a specific value.
This is done using the ‘startswith’ method.
This is assigned to a result.
This is displayed as output on the console.
