Python program – All occurrences of Substring from the list of strings

PythonServer Side ProgrammingProgramming

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.
