Input: s = @geeksforgeeks%
arr[] = {'o','e','%'}
Output: [true,true,true]
Input: s = $geek
arr[] = {'@','e','a','$'}
Output: [false,true,false,true]Method #1: using in keyword + loop
Traverse through the char array and for each character in arr check if that character is present in string s using in operator which returns a boolean value (either True or false).
Python3
# Python implementation to check string# for specific characters # function to check stringdef check(s, arr): result = [] for i in arr: # for every character in char array # if it is present in string return true else false if i in s: result.append("True") else: result.append("False") return result # Driver Codes = "@geeksforgeeks123"arr = ['e', 'r', '1', '7']print(check(s, arr)) |
Output
['True', 'True', 'True', 'False']
Method #2: Alternative method
Python3
# Python implementation to check string for# specific characters # function to check stringdef check(s, arr): # returns a list of booleans result = [characters in s for characters in arr] return result # Driver Codes = "@geeksforgeeks123"arr = ['e', 'r', '1', '@', '0']print(check(s, arr)) |
Output
[True, True, True, True, False]
