Sum Numbers

Quiz>

In a given text you need to sum the numbers. 

Only separated numbers should be counted. 

If a number is part of a word it shouldn't be counted.

 

The text consists from numbers, spaces and english letters

 

Input:

A string.

 

Output:

An int.

 

Example:

sum_numbers('hi') == 0
sum_numbers('who is 1st here') == 0
sum_numbers('my numbers is 2') == 2
sum_numbers('This picture is an oil on canvas '
'painting by Danish artist Anna '
'Petersen between 1845 and 1910 year') == 3755
sum_numbers('5 plus 6 is') == 11
sum_numbers('') == 0

 

def sum_numbers(text: str) -> int:
    # your code here
    return 0


if __name__ == '__main__':
    print("Example:")
    print(sum_numbers('hi'))

    # These "asserts" are used for self-checking and not for an auto-testing
    assert sum_numbers('hi') == 0
    assert sum_numbers('who is 1st here') == 0
    assert sum_numbers('my numbers is 2') == 2
    assert sum_numbers('This picture is an oil on canvas '
 'painting by Danish artist Anna '
 'Petersen between 1845 and 1910 year') == 3755
    assert sum_numbers('5 plus 6 is') == 11
    assert sum_numbers('') == 0
    print("Coding complete? Click 'Check' to earn cool rewards!")

 

Solve>

1. 입력값을 단어로 나눈다.

def sum_numbers(text: str):
    text_list = text.split()

 

2. 반환할 값을 초기 설정 한다.(숫자의 합)

def sum_numbers(text: str):
    result = 0

 

3. 각 단어마다 정수로 바꿔서 정수로 바꿔지면 정수를 i 변수에 할당하고 그 값을 반환할 값에 더한다.

def sum_numbers(text: str):
    for word in text_list:
        try:
            i = int(word)
            result += i

 

4. 그 외에 글자랑 숫자랑 같이 있는 경우에는 다음 것을 확인 한다.

def sum_numbers(text: str):
        except:
            pass

 

5. for문이 종료 되면 result를 반환한다.

def sum_numbers(text: str):
    return result

 

Code>

def sum_numbers(text: str):
    text_list = text.split()
    
    result = 0
    
    for word in text_list:
        try:
            i = int(word)
            result += i
        except:
            pass
            
    return result

 

Example>

if __name__ == '__main__':
    print("Example:")
    print(sum_numbers('hi'))

    # These "asserts" are used for self-checking and not for an auto-testing
    assert sum_numbers('hi') == 0
    assert sum_numbers('who is 1st here') == 0
    assert sum_numbers('my numbers is 2') == 2
    assert sum_numbers('This picture is an oil on canvas '
                       'painting by Danish artist Anna '
                       'Petersen between 1845 and 1910 year') == 3755
    assert sum_numbers('5 plus 6 is') == 11
    assert sum_numbers('') == 0
    print("Coding complete? Click 'Check' to earn cool rewards!")

 

Result>

Example:

0
