Write Python program for sub strings

Method #1 : Using list comprehension + string slicing

# Python3 code to demonstrate working of
# Get all substrings of string
# Using list comprehension + string slicing 
# initializing string
test_str = "Geeks"

# printing original string
print("The original string is : " + str(test_str)) 

# Get all substrings of string
# Using list comprehension + string slicing
res = [test_str[i: j] for i in range(len(test_str))for j in range(i + 1, len(test_str) + 1)]

# printing result
print("All substrings of string are : " + str(res))

Output
== RESTART: C:/Users/Student/AppData/Local/Programs/Python/Python37-32/x.py ==
The original string is : Geeks
All substrings of string are : ['G', 'Ge', 'Gee', 'Geek', 'Geeks', 'e', 'ee', 'eek', 'eeks', 'e', 'ek', 'eks', 'k', 'ks', 's']
