Answer 1

def SumAndAverage(str1):
    # A temporary string
    temp = "0"
    # holds sum of all numbers present in the string
    Sum = 0
    #counter of numbers in row
    count=0
    # read each char
    for ch in str1:
        # if  char is a digit
        if (ch.isdigit()):
            temp += ch
        # if current character is not digit
        else:
            if temp!="0":
                count+=1
            Sum += int(temp)
            # reset temporary string
            temp = "0"
    if str1[-1].isdigit():
        count+=1
    Sum += int(temp)
    # print sum of numbers
    print(Sum)
    # print average of nubers
    print(Sum / count)


# Main code

# input the string
print("Input the string")
str1 = input()
# Function call
SumAndAverage(str1)
