How do I check whether comma separated elements of a string are in the list or not?

a = "3"
b = ["3"]

def func():
    return a in b

The above function returns "TRUE"

But if I have my code as follows:

a="1,2,3,4"
b = ["3"]

How do I check the elements of a one by one with b, i.e, "1"==["3"] or "2"==["3"], and so on, and return "TRUE" when "3"==["3"]

>Solution :

Try this

a="1,2,3,4"
b = ["3"]


def func(a,b):
    return any(e in b for e in a.split(','))

print(func(a,b))

Output

True

• Use split(',') for converting string to list.
• Code inside the any() function e in b for e in a.split(',') returns a list of True and False based on condition, Here e values are 1, 2, 3, 4 one by one and check if e is in b list.
• Use the any() function, It returns True if one of the conditions is True in the list.
