Pylint 出现“模块中没有名称”错误

使用Pylint进行代码检查是Python开发中很常见的一项任务。Pylint可以帮助开发者找出代码中潜在的问题，并提供一些建议来提高代码质量。然而，有时候在运行Pylint时会出现"模块中没有名称"的错误。本文将介绍这个错误的原因，并提供解决方法。

python
def calculate_average(numbers):
    cout = 0
    for num in numbers:
        cout += num
    average = cout / len(numbers)
    return average
nums = [1, 2, 3, 4, 5]
print(calculate_average(nums))

python
def calculate_sum(numbers):
    total = 0
    for num in numbers:
        total += num
    return total
nums = [1, 2, 3, 4, 5]
print(total)  # 模块中没有名称错误
print(calculate_sum(nums))

python
from math import sqrt
def calculate_hypotenuse(a, b):
    hypotenuse = sqrt(a**2 + b**2)
    return hypotenuse
side_a = 3
side_b = 4
print(calculate_hypotenuse(side_a, side_b))  # 模块中没有名称错误

python
import math
def calculate_hypotenuse(a, b):
    hypotenuse = math.sqrt(a**2 + b**2)
    return hypotenuse
side_a = 3
side_b = 4
print(calculate_hypotenuse(side_a, side_b))

python
def calculate_sum(numbers):
    total = 0
    for num in numbers:
        total += num
    return total
nums = [1, 2, 3, 4, 5]
print(calculate_sum(nums))

python
import math
def calculate_hypotenuse(a, b):
    hypotenuse = math.sqrt(a**2 + b**2)
    return hypotenuse
side_a = 3
side_b = 4
print(calculate_hypotenuse(side_a, side_b))
