Python基础学习-问题排查

问题描述

执行程序时遇到错误：NameError:name‘XXX’is not defined

i = int(raw_input('输入利润:'))
arr = [1000000,600000,400000,200000,100000,0]
rat = [0.01,0.015,0.03,0.05,0.075,0.1]
r = 0
for idx in range(0,6):
    if i>arr[idx]:
        r+=(i-arr[idx])*rat[idx]
        print (i-arr[idx])*rat[idx]
        i=arr[idx]
print (r)

执行：
Traceback (most recent call last):
  File "D:/pythonProject/pythonProject3/.idea/新建包/1.py", line 5, in 
    i = int(raw_input('输入利润:'))
NameError: name 'raw_input' is not defined

原因分析：

其实是python3删除了raw_input，用等效的代码input替代即可

---

解决方案：

将raw_input改成input
