Question

我无法将参数传递给我的脚本。脚本启动命令行：myscript.py -c随机我在我的代码中使用了getopt（在那里给出）但是这段代码没有循环遍历参数，因为稍后在程序中没有定义tests_company varible，我哪里出错？

tested_company=None
try:
    opts, args = getopt.getopt(sys.argv[1:], "hc:i", ['help', 'company', 'info']) #first argument ignored because zabbix giving it and being useless
except getopt.GetoptError as e:
    print (e)
    usage()
    sys.exit(3)
if not opts:
    #print ('No options supplied, only updating the database')
    print("3")
    sys.exit(3)
else:
    for opt, arg in opts:
        if opt in ('-h', '--help'):
            usage()
            sys.exit(0)
        elif opt in ('-c', '--company'):
            tested_company = arg
        elif opt == '-i':
            displayInfos=1

我认为您在getopt调用中company之后错过了一个等号。这段代码适合我：

import getopt
import sys

tested_company=None
try:
    opts, args = getopt.getopt(sys.argv[1:], "hc:i", ['help', 'company=', 'info']) #first argument ignored because zabbix giving it and being useless
    print(opts)
except getopt.GetoptError as e:
    print (e)
    usage()
    sys.exit(3)
if not opts:
    #print ('No options supplied, only updating the database')
    print("3")
    sys.exit(3)
else:
    for opt, arg in opts:
        if opt in ('-h', '--help'):
            usage()
            sys.exit(0)
        elif opt in ('-c', '--company'):
            tested_company = arg
        elif opt == '-i':
            displayInfos=1

print(tested_company)

用

调用它

> python .\script.py -c xxxx

给出

[('-c', 'xxxx')]
xxxx

使用

进行通话

> python .\script.py --company xxxx

给出

[('--company', 'xxxx')]
xxxx

opts变量可能无法初始化，而是在try语句之外调用。你不能做以下任何特殊原因？

tested_company=None
try:
    opts, args = getopt.getopt(sys.argv[1:], "hc:i", ['help', 'company', 'info']) #first argument ignored because zabbix giving it and being useless
    if not opts:
        #print ('No options supplied, only updating the database')
        print("3")
        sys.exit(3)
    else:
        for opt, arg in opts:
            if opt in ('-h', '--help'):
                usage()
                sys.exit(0)
            elif opt in ('-c', '--company'):
                tested_company = arg
            elif opt == '-i':
                displayInfos=1
except getopt.GetoptError as e:
    print (e)
    usage()
    sys.exit(3)
