python - 如何在python脚本中调用cmd文件

Question

这是 python 脚本会做的。问题是如何在函数内部调用外部cmd文件？

• 读取目录中的 CSV 文件。
• 如果第 6 列的内容等于“已批准”，则调用外部窗口脚本“TransferProd.cmd”

.

def readCSV(x):
    #csvContents is a list in the global scope that will contain lists of the  
    #items on each line of the specified CSV file
    try:
        global csvContents
        file = open(csvDir + x + '.csv', 'r')      #Opens the CSV file
        csvContents = file.read().splitlines()     #Appends each line of the CSV file to csvContents
        #----------------------------------------------------------------------
        #This takes each item in csvContents and splits it at "," into a list.
        #The list created replaces the item in csvContents
        for y in range(0,len(csvContents)):
            csvContents[y] = csvContents[y].lower().split(',')
        if csvContents[y][6] == 'approved':
            ***CALL TransferProd.cmd***
            file.close()
        return
    except Exception as error:
        log(logFile, 'An error has occurred in the readCSV function: ' + str(error))
        raise

Answer 1

看看 subprocess module .

import subprocess
p = subprocess.Popen(['TransferProd.cmd'])

您可以指定输出/错误的去向(直接到文件或类似文件的对象)、管道输入等。
