AttributeError:"int"对象没有属性"replace" [英] AttributeError: 'int' object has no attribute 'replace'

问题描述

我想知道为什么在运行此代码时出现此错误:

# Ask user input
# Find out network device id for network device with ip or hostname, index 3 is device id
# In the loop until 'id' is assigned or user select 'exit'
id = ""
device_id_idx = 3
while True:
    user_input = input('=> Select a number for the device from above to show IOS config:')
    user_input= user_input.replace(" ","") # ignore space
    if user_input.lower() == 'exit': 
        sys.exit()
    if user_input.isdigit():
        if int(user_input) in range(1,len(device_show_list)+1):
            id = device_list[int(user_input)-1][device_id_idx]
            break
        else:
            print ("Oops! number is out of range, please try again or enter 'exit'")
    else:
        print ("Oops! input is not a digit, please try again or enter 'exit'")
# End of while loop

输出错误:

user_input= user_input.replace(" ","") # ignore space
AttributeError: 'int' object has no attribute 'replace'

该代码应接受输入并返回信息.预先感谢！

解决方案

如果您使用的是Python3.x，则input将返回一个字符串，您可以尝试调试代码以检查user_input或

print(type(user_input))

如果您使用的是Python2.x input，可能不是代码的好方法 因为input函数会评估您的输入.如果输入是1 2，则将得到SyntaxError: invalid syntax，如果输入是1，则将得到int对象，这就是您收到错误的原因. /p>

我建议使用raw_input，因为raw_input完全接受用户键入的内容，并将其作为字符串传递回去.

I am wondering why I have this error when I run this code:

# Ask user input
# Find out network device id for network device with ip or hostname, index 3 is device id
# In the loop until 'id' is assigned or user select 'exit'
id = ""
device_id_idx = 3
while True:
    user_input = input('=> Select a number for the device from above to show IOS config:')
    user_input= user_input.replace(" ","") # ignore space
    if user_input.lower() == 'exit': 
        sys.exit()
    if user_input.isdigit():
        if int(user_input) in range(1,len(device_show_list)+1):
            id = device_list[int(user_input)-1][device_id_idx]
            break
        else:
            print ("Oops! number is out of range, please try again or enter 'exit'")
    else:
        print ("Oops! input is not a digit, please try again or enter 'exit'")
# End of while loop

output error:

user_input= user_input.replace(" ","") # ignore space
AttributeError: 'int' object has no attribute 'replace'

This code is supposed to accept an input and return information. Thanks in advance!

解决方案

If you're using Python3.x input will return a string,you can try to debug your code to check the type of user_input or

print(type(user_input))

If you're using Python2.x input maybe is not a good way for your code because input function evaluates your input.If your input is 1 2 you will get SyntaxError: invalid syntax,and if your input is 1,and it will get int object,this is why you got the error.

I suggest raw_input because raw_input takes exactly what the user typed and passes it back as a string.
