Python set to check if string is panagram
Given a string, check if the given string is pangram or not.
Examples:
Input : The quick brown fox jumps over the lazy dog Output : The string is a pangram Input : geeks for geeks Output : The string is not pangram
A normal way would have been to use frequency table and check if all elements were present or not. But using import ascii_lowercase as asc_lower we import all the lower characters in set and all characters of string in another set. In the function, two sets are formed- one for all lower case letters and one for the letters in the string. The two sets are subtracted and if it is an empty set, the string is a pangram.
Below is Python implementation of the above approach:
# import from string all ascii_lowercase and asc_lower from string import ascii_lowercase as asc_lower # function to check if all elements are present or not def check(s): return set(asc_lower) - set(s.lower()) == set([]) # driver code strng ="The quick brown fox jumps over the lazy dog"if(check(strng)== True): print("The string is a pangram") else: print("The string isn't a pangram") |

Output:
The string is a pangram
