VS Code 中的 Python 告诉我一个数字小于一个较小的数字

Question

This code was written in VS Code, Python. I have a minimum variable in my code and another variable. Let's call them X and Xmin. I give Xmin and X numbers. Then when I compare them with < my code tells me that the smaller one is larger. Here is my code

Xmin = 100
print("X")
X = input()
if X < Xmin:
    print("X is too small.")

The problem is when I make X = 500, it will tell me that X is greater than Xmin, but when I give X something really big, like 1000000, it will tell me that X is too small.

Answer 1

If you are using python 3, you need to add an int() around the input statement in order for python to know the user input should be a number, not a string:

try:

    Xmin = 100
    print("X")
    X = int(input())
    if X < Xmin:
        print("X is too small.")

except:
    print('That is not an integer.')

If you are using python 2, watch out, input() in python 2 is the equivalent of eval(input()) in python 3. and we all know that 'eval is evil'.

Answer 2

X = input() #takes input as string

Use below code instead of above:

X = int(input()) #takes input as integer
