Is it possible to return True in for loop?

Question

In this code, I am taking two numbers in the list and checking whether it is adding up to K. The only problem is that I am not able to return True.

but if I use the print function instead of return it works. Is there some constraint that I cannot use return type in for loop or conditions?

def funcSum():
    NumList = []

    Number = int(input("Please enter the total number of list elements: "))
    for i in range(1, Number + 1):
        value = int(input("Please enter the value of %d element : " %i))
        NumList.append(value)

    k = int(input("Enter the value of K: "))

    for i in range (Number):
        for j in range(i + 1, Number):
            if NumList[i] + NumList[j] == k:
                return True
                break
funcSum()

I want to return True if two numbers add up to K or it will return False.

if you want to use your original code :

def funcSum():
    NumList = []

    Number = int(input("Please enter the total number of list elements: "))
    for i in range(1, Number + 1):
        value = int(input("Please enter the value of %d element : " %i))
        NumList.append(value)

    k = int(input("Enter the value of K: "))
    equal = False
    for i in range (Number):
        for j in range(i + 1, Number):
            if NumList[i] + NumList[j] == k:
                equal = True
                break
        if equal:
            break
    return equal

but you can also do this with the last bit:

    equal = False
    for i in list(NumList):
        for u in list(NumList):
            if i == u:
                equal = True
                break
        if equal :
            break

hope it helps :)
