# Write a function, called sumEven,
# that takes a list of strings as its argument.
# Each string may be either letter or an integer.
# A sum of all even integers. If there is no even integers, return 0
#
# You may use isdigit() which
# returns true if there is at least one character in a given string
# and all characters in the string are digits, false otherwise.
#
# A sample run would be
#
# print(sumEven(['12', 'A', '8', 'e', '5']))
# 20
#
# print(sumEven([A, 1, e, 5, 3, 1111, cs]))
# 0
#
# You may assume the list is non-empty, no tie, non negative integers
# but you may not make any other assumptions about the list.


def sumEven(lst):
    result = 0

    for i in lst:
        if (i.isdigit()) and (int(i) % 2 == 0):
            result += int(i)

    return result
