虽然类型比较在终端中有效,但断言在脚本中无效

我遇到了一个比较奇怪的问题。

%run decodage_parametres_script.py -r junit,html

python脚本选项解析用于填充字典,结果是:

{'-cli-no-summary': False, '-cli-silent': False, '-r': ['junit', 'html']}

for i in current_options['-r']:
    # for each reporter required with the -r option:
    #    - check that a file path has been configured (otherwise set default)
    #    - create the file and initialize fields
    print("trace i", i)
    print("trace current_options['-r'] = ", current_options['-r'])
    print("trace current_options['-r'][0] = ", current_options['-r'][0])

    if current_options['-r'][i] == 'junit':
        # request for a xml report file
        print("request xml export")
        try:
            xml_file_path = current_option['--reporter-junit-export']
            print("xml file path = ", xml_file_path)
        except:
            # missing file configuration
            print("xml option - missing file path information")
            timestamp = get_timestamp()
            xml_file_path = 'default_report' + '_' + timestamp + '.xml'
            print("xml file path = ", xml_file_path)
        if xml_file_path is not None:
            touch(xml_file_path)
            print("xml file path = ", xml_file_path)
        else:
            print('ERROR: Empty --reporter-junit-export path')
            sys.exit(0)
    else:
        print("no xml file required")    

trace i junit
trace current_options['-r'] =  ['junit', 'html']
trace current_options['-r'][0] =  junit

In [557]: for i in current_options['-r']:
 ...:     print(i, type(i))
 ...:
junit <class 'str'>
html <class 'str'>

In [558]: toto = 'junit'

In [559]: type(toto)
Out[559]: str

In [560]: toto
Out[560]: 'junit'

In [561]: toto == current_options['-r'][0]
Out[561]: True

所以我的主张 if current_options['-r'][i] == 'junit' 我是否错过了一些琐碎的事情(

有人能帮我吗?
