如何在嵌套循环中正确设置用于while语句的可迭代元素？

Question

我正在尝试为嵌套循环设置一个可迭代元素，它的第一个可迭代元素的目的是print('just a test')，而对于其他循环则打印一个连接的字符串。

这是一次尝试：

states=['Alabama', 'Georgia']
titles=['president', 'secretary']
codes=['A80', 'A81']

for index, state in enumerate(states, start=0):
   for index, title in enumerate(titles, start=0):
        for index, code in enumerate(codes, start=0):
             if index==0:
                 print('just a test')
             else:
                 print(state +'-'+title+'-'+code) 

它返回：

#just a test
#Alabama-president-A81
#just a test
#Alabama-secretary-A81
#just a test
#Georgia-president-A81
#just a test
#Georgia-secretary-A81

预期输出：

#this is a test
#A81-president-Alabama
#A80-secretary-Alabama
#A81-secretary-Alabama
#A80-president-Georgia
#A81-president-Georgia
#A80-secretary-Georgia
#A81-secretary-Georgia

如何重命名可迭代元素？

Answer 1

看起来你有不适当的缩进级别。

states=['Alabama', 'Georgia']
titles=['president', 'secretary']
codes=['A80', 'A81']

for state in states:
    for title in titles:             #4 spaces
         for code in codes:          #4 spaces
            while i==0:              #3 spaces
                print('just a test') #4 spaces
               if i > 0:             #3 spaces
                 continue            #2 spaces
               print(state+'-'+title+'-'+code) #3 spaces

适当的缩进：

states=['Alabama', 'Georgia']
titles=['president', 'secretary']
codes=['A80', 'A81']

for state in states:
    for title in titles:
         for code in codes:
             while i==0:
                 print('just a test')
                 if i > 0:
                     continue
                 print(state+'-'+title+'-'+code) 

此外，您从未定义过i，因此您需要修复它。
