Is there any ways to check if any chars from a string are in another string without using loops-CodePudding

I'm trying to determine if any characters from a string1 are in another string2

example:
string1 = "abcdefghijklmnopqrstuvwxyz"

any of the characters from this string1 are in this string2 for example:

string2="HELLO WoRLD"

but i want to do so without using any loops, is there anything that can be done in python maybe using the in statement

CodePudding user response：

You can do it using sets

str1 = 'abcd'
str2 = 'bcde'

set1 = set(str1) 
set2 = set(str2)

if set1.intersection(set2):
    print('There are same chars in the strings')

CodePudding user response：

For this example, you can use set.intersection:

out = list(set(string1).intersection(string2))

Output:

['o']

CodePudding user response：

you could do something like this:

string1 = "abcdefghijklmnopqrstuvwxyz"
string2="HELLO WoRLD"
#define a list that will contain the characters in common
chars_in_common = []
for char in string1:
    #looping trough the string to find characters that are in common
    if char in string2:
        # updating list
        chars_in_common.append(char)
print(chars_in_common)

Output:

['o']
