Why is this the wrong?(python)-CodePudding

with open("info.txt", "r") as file:
for line in file:
    (name, weight, height) = line.strip().split(", ")
    if (not name) or (not weight) or (not height):
        continue

    
    bmi = int(weight) / ((int(height) / 100) **2)
    result = ""
    if 25 <= bmi:
        result = "과체중"
    elif 18.5 <= bmi:
        result = "정상 체중"
    else:
        result = "저체중"


    print('\n'.join([
        "이름: {}",
        "몸무게: {}",
        "키: {}",
        "BMI: {}",
        "결과: {}"
    ]).format(name, weight, height, bmi, result))
    print()

error message:

Traceback (most recent call last): File "c:\Users\cnhan\My_project\python\tempCodeRunnerFile.py", line 4, in (name, weight, height) = line.strip().split(", ") ValueError: too many values to unpack (expected 3)

CodePudding user response：

Check what is the length of array returned by line.strip().split(", "). The error occured because it returned more than 3 values (name, weight, height).

If it happens that some lines may return more than 3 values, but you want only the first three then you can add the * operator in the end.

Like this

(name, weight, height, *_) = line.strip().split(", ")
