Question

我遇到的问题是我的脚本返回到此程序中的第一个for循环，现在它只返回到第二个。我试图弄清楚如何通过所有步骤强制它。

提前致谢

import copy

test = {'AEP': {'days': [1]}, 'AES': {'days': [32]},'AIS': {'days': [7]},'TWO': {'days': [35]}}

print (test)
for stock in test:
    a = stock
    print ("step one")
    for stock in test.itervalues():
        print ("step two")
        for days in stock.itervalues():
            print ("step three")
            for i in days:
                print ("step four")
                if i <= 30:
                    days[days.index(i)] = i + 1
                else:
                    test_2 = copy.deepcopy(test)
                    test_2.pop(a)
                    print (str(a) + " Has been removed")
                    test = copy.deepcopy(test_2)

print (test)

当前流量/日志：

{'AEP': {'days': [1]}, 'AES': {'days': [32]}, 'TWO': {'days': [35]}, 'AIS': {'days': [7]}}
step one
step two
step three
step four
step two
step three
step four
AEP Has been removed
step two
step three
step four
Traceback (most recent call last):
  File "fortest.py", line 19, in <module>
    test_2.pop(a)

以下是我希望看到的最终结果

test = {'AEP': {'days': [1]},'AIS': {'days': [7]}}

Answer 1

所以我继续将第一个for循环与第二个循环结合起来，这样变量仍然与它到达if和else语句的变量相同。

import copy

test = {'AEP': {'days': [1]}, 'AES': {'days': [32]},'AIS': {'days': [7]},'TWO': {'days': [35]}}


print (test)
for stock,stock_name in zip(test.itervalues(),test):
    a = stock_name
    print ('step one')
    for days in stock.itervalues():
        print ("step two")
        for i in days:
            print ("step three")
            if i <= 30:
                days[days.index(i)] = i + 1
            else:
                test_2 = copy.deepcopy(test)
                test_2.pop(a)
                print (str(a) + " Has been removed")
                test = copy.deepcopy(test_2)

print (test)

当前流量/日志：

{'AEP': {'days': [1]}, 'AES': {'days': [32]}, 'TWO': {'days': [35]}, 'AIS': {'days': [7]}}
step one
step two
step three
step one
step two
step three
AES Has been removed
step one
step two

TWO Has been removed

{'AEP': {'days': [2]}, 'AIS': {'days': [7]}}

for循环不返回第一个forloop
