问题描述
我正在尝试从控制台运行一个模块.我的目录结构是这样的:
I am trying to run a module from the console. The structure of my directory is this:
我正在尝试从 problem_set_02
目录运行模块 p_03_using_bisection_search.py
,使用:
I am trying to run the module p_03_using_bisection_search.py
, from the problem_set_02
directory using:
$ python3 p_03_using_bisection_search.py
p_03_using_bisection_search.py
里面的代码是:
__author__ = 'm'
from .p_02_paying_debt_off_in_a_year import compute_balance_after
def compute_bounds(balance: float,
annual_interest_rate: float) -> (float, float):
# there is code here, but I have omitted it to save space
pass
def compute_lowest_payment(balance: float,
annual_interest_rate: float) -> float:
# there is code here, but I have omitted it to save space
pass
def main():
balance = eval(input('Enter the initial balance: '))
annual_interest_rate = eval(input('Enter the annual interest rate: '))
lowest_payment = compute_lowest_payment(balance, annual_interest_rate)
print('Lowest Payment: ' + str(lowest_payment))
if __name__ == '__main__':
main()
我正在导入一个位于 p_02_paying_debt_off_in_a_year.py
中的函数,其代码是:
I am importing a function that is in p_02_paying_debt_off_in_a_year.py
which code is:
__author__ = 'm'
def compute_balance(balance: float,
fixed_payment: float,
annual_interest_rate: float) -> float:
# this is code that has been omitted
pass
def compute_balance_after(balance: float,
fixed_payment: float,
annual_interest_rate: float,
months: int=12) -> float:
# Omitted code
pass
def compute_fixed_monthly_payment(balance: float,
annual_interest_rate: float) -> float:
# omitted code
pass
def main():
balance = eval(input('Enter the initial balance: '))
annual_interest_rate = eval(
input('Enter the annual interest rate as a decimal: '))
lowest_payment = compute_fixed_monthly_payment(balance,
annual_interest_rate)
print('Lowest Payment: ' + str(lowest_payment))
if __name__ == '__main__':
main()
我收到以下错误:
ModuleNotFoundError: No module named '__main__.p_02_paying_debt_off_in_a_year'; '__main__' is not a package
我不知道如何解决这个问题.我已经尝试添加一个 __init__.py
文件,但它仍然不起作用.
I have no idea how to solve this issue. I have tried adding a __init__.py
file, but it is still not working.
推荐答案
只需删除相对导入的点并执行:
Simply remove the dot for the relative import and do:
from p_02_paying_debt_off_in_a_year import compute_balance_after
这篇关于ModuleNotFoundError:__main__ 不是包是什么意思?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
