Question

我正在尝试制作代数节目，但即使我输入了正确的答案，也会打印错误的

x= random.randrange(1, 100)
x2 = random.randrange(1, 100)
answer = input('if x + ' + str(x2) + ' = ' + str(x + x2) + ' what is x equal to? ')
ranswer = x + x2
if answer == ranswer:
   print('correct')
else:
   print('incorrect')

NVM GUYS我只是愚蠢应该做ranswer = x ：P

Answer 1

x= random.randrange(1, 100)
x2 = random.randrange(1, 100)
answer = input('if x + ' + str(x2) + ' = ' + str(x + x2) + ' what is x equal to? ')
if int(answer) == x:
   print('correct')
else:
   print('incorrect')

正如马利克所说，你的逻辑存在问题。我解决了这个问题，并将answer变量转换为整数，以便正确比较。

Answer 2

监控你的代码（python 2.7）

#exam_plus.py 
import random

x= random.randrange(1, 100)
x2 = random.randrange(1, 100)
answer = raw_input('if x + ' + str(x2) + ' = ' + str(x + x2) + ' what is x equal to? ')
ranswer = x + x2
print "answer", answer
print "correct answer", ranswer #it is obviously not correct, i just put it to show what your program expects

if int(answer) == ranswer:
   print'correct'
else:
   print 'incorrect'

运行它

$ python exam_plus.py 
if x + 52 = 55 what is x equal to? 3
answer 3
correct answer 55
incorrect

$ python exam_plus.py 
if x + 81 = 88 what is x equal to? 7
answer 7
correct answer 88
incorrect

$ python exam_plus.py 
if x + 3 = 71 what is x equal to? 68
answer 68
correct answer 71
incorrect

这意味着您的问题逻辑不正确 - 您应该编辑ranswer=x，这将导致

$ python exam_plus.py 
if x + 12 = 72 what is x equal to? 60
answer 60
correct answer 60
correct

$ python exam_plus.py 
if x + 24 = 61 what is x equal to? 37
answer 37
correct answer 37
correct

$ python exam_plus.py 
if x + 88 = 151 what is x equal to? 63
answer 63
correct answer 63
correct

Python if语句总是打印不正确
