有没有一种可行的pythonic方法可以通过forloops获得输出

Question

我需要打印那些用for循环beyond打印出来的上半部分中创建的值对，以便在程序增长时动态添加一些新变量

打印到cli应该如下所示

[vargroup] 
Varname:Varvalue
... 
[vargroup1] 
Varname:Varvalue
... 

我现在在这里坐了很长时间，尝试了不同的东西，但在大多数情况下，它说了一些关于整数和切片、元组的东西，并且forloop不能处理ListIndex。。。我对python甚至编程都很陌生，我真的不明白解释器想从我这里得到什么。。。现在我的朋友告诉我你可以帮助我：哦

import configparser



def test():
#defining Arrays for Settingmanipulation
#default group



    default_rel = []
    default_rel.append('DEFAULT')

#program specific group
#define
    program_rel_name = []
    program_rel_val = []


    program_rel = [program_rel_name, program_rel_val]
    program_rel_name.append("")

#example for a vargroup
program_rel_val.append('OPERATIONAL')       #Name
    program_rel_name.append("FileName")
    program_rel_val.append('settings.ini')      #inifile Name
    program_rel_name.append("WorkDir")
    program_rel_val.append('..')                #workdir

#data related group
    data_rel_name = []
    data_rel_val = []

    data_rel = [data_rel_name, data_rel_val]
    data_rel_name.append("")
    data_rel_val.append ('DATA')  # Name
    data_rel_name.append("aIndex")
    data_rel_val.append ('sp500')  # aindex
    data_rel_name.append("dataSetType")
    data_rel_val.append ('jk')  # dataSet (joined Closes)
    data_rel_name.append("joinData")
    data_rel_val.append('True')         #mData (join those Closes)
    data_rel_name.append("visualizeData")
    data_rel_val.append('True')         #(v )run Visualizer

#maschine learning related
    ml_rel_name = []
    ml_rel_val = []

    ml_rel = [ml_rel_name, ml_rel_val]
    ml_rel_name.append("")
    ml_rel_val.append("MaschineLearning")   #Name
    ml_rel_name.append("runMlPreprocessor")
    ml_rel_val.append('True')               #run ml preprocessor


    inifile = [program_rel, data_rel, ml_rel]



#writing inifile
    config = configparser.ConfigParser ()
    cinfig ={}
    Group=1
    ValuePair=3
#output shall be to cli like demonstrated with this print
    print(inifile[Group][0][ValuePair] + ":"+ inifile[Group][1][ValuePair])
    print()
    print()

#by this forloop
    for count, Groups in enumerate(inifile):
        for counti, ValuePairs in inifile[count]:
            print(inifile[count][0][counti] + ": " + inifile[count][1][counti])



test()

在这段代码中，我设计了一个for循环来打印存储在多维数组中的那些值对。。。。现在，4小时后，我试图以param:value格式安排所需的输出，我很难放弃。。。 你知道怎么做吗

由于在该类中创建了数组，因此给出了示例输入。第69行中的输出是一个错误，该错误表示

 for counti, ValuePairs in inifile[count][0]: ValueError: not enough values to unpack (expected 2, got 0) 

Answer 1

我认为使用名称和值的分隔列表太复杂了，现在必须使用zip()来创建带有名称和值的pair

for all_names, all_values in inifile:
    for name, value in zip(all_names, all_values):
        print('{}: {}'.format(name, value))

您可以使用tuples(name, value)使它更简单

def test():
    default_rel = [
        ('', 'DEFAULT'),
    ]

    program_rel = [
        ("", 'OPERATIONAL'),
        ("FileName", 'settings.ini'),
        ("WorkDir", '..'),
    ]

    data_rel = [
        ("", 'DATA'),
        ("aIndex", 'sp500'),
        ("dataSetType", 'jk'),
        ("joinData", True),
        ("visualizeData", True),
    ]

    ml_rel = [
        ("", "MaschineLearning"),
        ("runMlPreprocessor", True),
    ]

    inifile = [program_rel, data_rel, ml_rel]

    for group in inifile:
        for name, value in group:
            print('{}: {}'.format(name, value))

test()
