Python | Check if a string contains an element from a list

Method # 1: Using List Comprehension
This problem can be solved by using list comprehension, in this we check the list, and also by using string elements if we can find a match. and return true if we find one and false does not use conditional statements.

# Python3 demo code
# check if the string contains a list item
# use comprehension list

 
# initialization string

test_string = " There are 2 apples for 4 persons "

  
# initializing the test list

test_list = [ `apples` , `oranges` ]

 
# print original line

print ( "The original string:" + test_string)

 
# print the original list

print ( "The original list:" + str (test_list))

 
# using comprehension list
# check if the string contains a list item

res = [ele for ele in test_list if (ele in test_string)]

  
# print result

print ( " Does string contain any list element: " + str ( bool (res)))

Output: 

 The original string: There are 2 apples for 4 persons The original list: [`apples`,` oranges `] Does string contain any list element: True

Method # 2: using any()
Using any function is the most classic way in which you can accomplish this task, as well as efficiently. This function checks for a match in line with the match of each list item.

# Python3 demo code
# check if string contains a list item
# use comprehension list

 
# initializing string

test_string = "There are 2 apples for 4 persons"

 
# initialize the test list

test_list = [ `apples` , ` oranges ` ]

 
# print original line

print ( " The original string: " + test_string)

 
# print the original list

print ( "The original list : " + str (test_list))

 
# using comprehension list
# check if the string contains a list item

res = any (ele in < / code> test_string for ele in test_list)

 
# print result

print ( " Does string contain any list element: " + str (res)

Output: 

 The original string: There are 2 apples for 4 persons The original list: [`apples`,` oranges`] Does string contain any list element: True
