Python Check If String Contains Certain Characters

Chapter: Python Last Updated: 30-05-2023 13:16:49 UTC

Program:

            /* ............... START ............... */
                
#Using the in operator:

string = "Hello, World!"
characters = "lo"

if any(char in string for char in characters):
    print("String contains at least one of the characters.")
else:
    print("String does not contain any of the characters.")




# Using the any() function with a generator expression:

string = "Hello, World!"
characters = "lo"

if any(char in string for char in characters):
    print("String contains at least one of the characters.")
else:
    print("String does not contain any of the characters.")




# Using a loop:

string = "Hello, World!"
characters = "lo"
contains_characters = False

for char in characters:
    if char in string:
        contains_characters = True
        break

if contains_characters:
    print("String contains at least one of the characters.")
else:
    print("String does not contain any of the characters.")

                /* ............... END ............... */
        

Output

String contains at least one of the characters.

Notes:

  • All these approaches check if any of the characters in the given string are present in the target string. You can replace "lo" in the above examples with any set of characters you want to check for.
