Question

Define a function called AddEvenPosDigs(string), which takes a string (with symbols and characters) as an argument, and returns an integer.

This function should add the digits of a string that are in an even position.

If there are no digits, the function should return -1.

As an example, the following code fragment:

string = "a12b056jk"; result=AddEvenPosDigs(string); print(result)

should produce the output:

8

thanks for posting the question, here is the function that adds up the digits found in the even positions

__________________________________________________________________________________________________

def AddEvenPosDigs(string):
    sum=-1
    for i in range(len(string)):
        if i%2==0 and string[i].isdigit():
            sum+=int(string[i])
    if sum==-1:
        return sum
    else:
        return sum+1

string = "a12b056jk"
result=AddEvenPosDigs(string)
print(result)
