我正在编写一个必须接受用户输入的程序.
#note: Python 2.7 users should use `raw_input`, the equivalent of 3.X's `input`
age = int(input("Please enter your age: "))
if age >= 18:
print("You are able to vote in the United States!")
else:
print("You are not able to vote in the United States.")
如果用户输入合理数据,这将按预期工作.
C:\Python\Projects> canyouvote.py
Please enter your age: 23
You are able to vote in the United States!
但如果他们犯了错误,那就崩溃了:
C:\Python\Projects> canyouvote.py
Please enter your age: dickety six
Traceback (most recent call last):
File "canyouvote.py", line 1, in …我想在问一些上下文之前提供我的代码.
我的代码:
a = float(input('Insert the value for a: '))
b = float(input('Insert the value for b: '))
c = float(input('Insert the value for c: '))
if type(a) != (float() or int()):
print ('You didn\'t insert a number! Try again! This is your last chance or I will stop running!')
sleep(1)
print (a)
if type(b) != (float() or int()):
print ('You didn\'t insert a number! Try again! This is your last chance or I will stop running!')
sleep(1)
print (b) …
