从python中的另一个文件调用函数

Question

我有一个名为 function_bucket.py 的 python 文件，我需要将 import modalprem() 函数转换为另一个名为 Array1.py 的文件。下面我提到了这两个函数的代码，但是在调用函数“No module named modalprem()”时，我看到了错误！。请帮我解决这个错误。

function_bucket.py 的代码

def main():
    def modalprem():
        return 1
if __name__ == "__main__":
    main()

Array1.py 的代码

import numpy as np
from Function_Bucket import modalprem()
modalprem()
def main():
    EA=50
    PT = 15
    PPT = 5
    AP = 50000
    Mode = 12
    PM = np.arange(12*PT+1)
    PY = np.arange(12*PT+1)
    AGE = np.arange(12*PT+1)
    PREM = np.arange(12*PT+1)
    i=1
    Modal_Premium = modalprem()
    print(Modal_Premium)
    if (Mode == 1):
        Modal_Premium = AP
    elif (Mode==2):
        Modal_Premium = AP *0.5131
    elif (Mode==4):
        Modal_Premium = AP *0.2605
    elif (Mode==12):
        Modal_Premium = AP *0.0886
        
    while(i <180):
        PM[i] = i
        PY[i] = int( (i+11)/12)
        AGE[i] = EA + PY[i] -1
        if (PM[i]<=PPT*12 and ((PM[i]-1)%(12/Mode) == 0)):
            PREM[i] = Modal_Premium
        else:
            PREM[i] = 0
        i = i+1
    print(PM)
    print(PY)
    print(AGE)
    print(PREM)
if __name__ == "__main__":
    main()

谢谢

我们将不胜感激！

Answer 1

您还在导入函数中添加括号 我认为这就是您收到此错误的原因

在你的 Array1.py

中试试这个

import function_bucket

function_bucket.modalprem()

您在function_bucket 中定义的函数是main，而不是modal_prem。您需要在 main 之外定义它

function_bucket.main()

您还在导入函数中添加括号

如果它不起作用，则意味着您没有共享正确的 Python 文件名

Answer 2

function_bucket.py 的代码

def main():
    def modalprem():
        return 1
    return modalprem

Array1.py 的代码

import numpy as np
from function_bucket import main
modalprem=main()
def main():
    EA=50
    PT = 15
    PPT = 5
    AP = 50000
    Mode = 12
    PM = np.arange(12*PT+1)
    PY = np.arange(12*PT+1)
    AGE = np.arange(12*PT+1)
    PREM = np.arange(12*PT+1)
    i=1
    Modal_Premium = modalprem()
    print(Modal_Premium)
    if (Mode == 1):
        Modal_Premium = AP
    elif (Mode==2):
        Modal_Premium = AP *0.5131
    elif (Mode==4):
        Modal_Premium = AP *0.2605
    elif (Mode==12):
        Modal_Premium = AP *0.0886

    while(i <180):
        PM[i] = i
        PY[i] = int( (i+11)/12)
        AGE[i] = EA + PY[i] -1
        if (PM[i]<=PPT*12 and ((PM[i]-1)%(12/Mode) == 0)):
            PREM[i] = Modal_Premium
        else:
            PREM[i] = 0
        i = i+1
    print(PM)
    print(PY)
    print(AGE)
    print(PREM)
if __name__ == "__main__":
    main()

希望这会按预期工作！
