python - 试图比较两个列表或一个相同的列表

Question

import random
b=[]
o=[]
v=0
g=2
y=0
V=0
q=0
compat=0
alex=[]
zach=[]
while v != 5:
    name="name"
    position="position"
    answers=[]
    for i in range(10):
        answer=random.randint(1,4)
        answers.append(answer)
    b.append(name)
    b.append(position)
    b.append(answers)
    v+=1
print(b)
for ii in range(0,5):
    t=b[g]
    o.append(t)
    g+=3
    l=len(o)
for iii in list(o):
    C = o[y]
    y = y + 1
    alex = []
    for iiii in range(5):
        I = 0
        compat=0
        R=o[q]
        V=0
        Y = C[V]
        for iiiii in range(10):
            r=R[I]
            if r == Y:
                compat+=1
            else:
                compat=compat
            I+=1
            V += 1
            print(compat)
        alex.append(compat)
        print(alex)
    zach.append(alex)
    q+=1
w=len(zach)
print(zach)
print(w)

这是我的代码，它工作得很好。但它应该将每个值与其他值相对，但它不只是放置相同的 Y 值并且不会改变。我已经把 v+=1 放在很多不同的地方，并围绕着几个变量移动，但它没有改变。5 个人应该有 25 个不同的答案，但它不只是打印相同的数字 5 次然后重新启动。任何帮助将不胜感激编辑：这就是我将上面的代码集成到

你增加了太多的噪音。

for iii in list(o):
    C = o[y]
    y = y + 1

你为什么不简单地使用你刚刚创建的变量？它会自动递增

for iii in list(o):
    C = o[iii]

您应该学习如何使用循环和其他一些基础知识。python 官方网站上有很好的教程。这里是for 循环之一。您的大多数变量的存在只是为了重复您已经在做的事情。

我避免了一些高级构造，但我离开了 zip。

import random

mentees = []
names = ['zach', 'alex', 'fred', 'jane', 'sara']

for name in names:
    mentee = dict()
    mentee['name'] = name
    mentee['compatibility'] = []
    answers = []
    for i in range(10):
        answers.append(random.randint(1,4))
    mentee['answers'] = answers
    mentees.append(mentee)

for mentee1 in mentees:
    m1_answers = mentee1['answers']
    for mentee2 in mentees:
        m2_answers = mentee2['answers']
        compat = 0
        # zip fuses both lists into one
        for m1_answer, m2_answer in zip(m1_answers, m2_answers):
            if m1_answer == m2_answer:
                compat += 1
        mentee1['compatibility'].append((mentee2['name'], compat))

print(mentees)
