Question

我下载了一个由三个文件组成的python脚本：

file1.py
file2.py
file3.py

我通常使用如下命令调用脚本：

python file1.py arg1 arg2 -n arg3 arg4

现在我想从另一个python文件file4.py中调用这个脚本，但我不知道应该如何提供这些参数。

在file1.py中我有：

import time
import file2
import file3

def main():
    variable1, variable2, variable3 = file2.parse_args()
    ...
    run_simulation(variable1, variable2, variable3)

def run_simulation(variable1, variable2, variable3):
    ...
    return 

if __name__ == '__main__':
    main()

和file2.parse_args（）类似于：

def parse_args():
    parser = argparse.ArgumentParser(
        description="Desc1")
    parser.add_argument("variable1", nargs="*", type=str,
                        help="Help")
    parser.add_argument("-b", "--byte", nargs="*", type=str, metavar="byte",
                        help="Help2")
    parser.add_argument("-e", "--exact", action="store_true",
                        help="Help3")
    # Parse command line arguments and check for errors
    args = parser.parse_args()
    error_check_arguments(args)

    [...]
    variable1, variable2 = None, None
    if not args.input:
        variable1, variable2 = parse_cards(args.variable1, args.variable2)
    return variable1, variable2, variable3

那么我应该在file4.py中放置什么代码才能运行这个脚本，就像我从命令行运行它一样？

Answer 1

如果忽略文件2的参数解析功能，并且只是希望将参数从调用文件1传递给文件4中的函数，那么元组似乎是Pythonic。所以这段代码可以添加到文件1中：

    For k = 1 To 6
        If k <> 2 Then
            Dim nc As New DataGridViewTextBoxColumn
            nc.Name = ""
            Myinputable.Columns.Add(nc)
        Else
            Myinputable.Columns.AddRange(combocol)
        End If
    Next k

    ' now add the rows and place the spreadsheet on the form

    Myinputable.Rows.Add(nobj - 1)
    Myinputable.Location = New Point(25, 50)

    Myinputable.AutoSize = True
    Me.Controls.Add(Myinputable)
    FlowLayoutPanel1.Visible = True

    Myinputable.Columns(0).Name = "Name"
    Myinputable.Columns(0).HeaderText = "Name"

    Myinputable.Columns(1).Name = "Type"
    Myinputable.Columns(1).HeaderText = "Type"

    Myinputable.Columns(2).Name = "LThresh"
    Myinputable.Columns(2).HeaderText = "Lower Threshold"
    'Myinputable.Columns(2).ValueType = co

    Myinputable.Columns(3).Name = "UThresh"
    Myinputable.Columns(3).HeaderText = "Upper Threshold"

    Myinputable.Columns(4).Name = "ABMin"
    Myinputable.Columns(4).HeaderText = "Abs. Minimum"

    Myinputable.Columns(5).Name = "ABMax"
    Myinputable.Columns(5).HeaderText = "Abs. Maximum "

    Myinputable.Rows(0).Cells(0).Value = "Help"

    If Myinputable.Capture = True Then
        MsgBox(" damn ")
    End If
  End Sub

Answer 2

更改main函数，使其将变量作为参数。

def main(variable1, variable2m variable2):
    ...

将解析args的代码移动到if __name__ == '__main__'块。

if __name__ == '__main__':
    variable1, variable2, variable3 = file2.parse_args()
    main(variable1, variable2, variable3)

您现在可以从其他模块调用main函数：

from file1 import main
main('variable1', 'variable2', 'variable3')

如何替换parse_args参数？
