Question

我应该将此处作为输入的两个数字进行比较。我的问题是，无论输入多少，我只能得到一个输出。我想我在列表迭代的某个地方出错了。还请告诉我，如果我在[A]和[B]中使用“ for i”而不是“在range（len（A））中的i”“为什么会出错？

import math
T = int(raw_input())
A = []
B = []
for i in range(0,T):
 a,b = raw_input().split()
 a = int(a)
 b = int(b)
A.append(a)
B.append(b)
k = len(A)
for i in range(k):                 
    if A[i] > B[i]:
      print ">"
    elif A[i] < B[i]:
      print "<"
    elif A[i] == B[i]:
      print "="

Answer 1

在我看来是一个意向性问题。确保在for循环中有A.append(a)

import math
T = int(raw_input())
A = []
B = []

for i in range(0,T):
    a,b = raw_input().split()
    a = int(a)
    b = int(b)
    A.append(a)
    B.append(b)

# k = len(A)
for i in range(len(A)):                 
    if A[i] > B[i]:
      print ">"
    elif A[i] < B[i]:
      print "<"
    elif A[i] == B[i]:
      print "="

为什么我的代码只给出一个输出？
