Python – All occurrences of Substring from the list of strings
When it is required to get all the occurrences of a substring from the list of strings, a simple list comprehension and the ‘startswith’ method is used.
Example
Below is a demonstration of the same −
my_string = "Is python fun to learn?"
print("The list is :")
print(my_string)
substring = "pyt"
print("The substring is :")
print(substring)
my_result = [i for i in range(len(my_string)) if my_string.startswith(substring, i)]
print("The result is :")
print(my_result)Output
The list is : Is python fun to learn? The substring is : pyt The result is : [3]
Explanation
A string is defined and is displayed on the console.
Another substring is defined and displayed on the console.
A list comprehension is used to iterate over the string.
The ‘startswith’ method is used to check if the string begins with a specific pattern/substring.
If yes, it is added to a variable after converting to a list.
This is displayed as output on the console.
