Python新手在Grok Learning课程中遭遇整数字符串转字符失败及AttributeError错误求助

Hey there! Let's break down what's going wrong with your code and get it working properly.

What's Causing the Error? #

The key mistake is in your first line: you're converting the user's input directly to an int with values = int(input("Codes: ")). But integers don't have a split() method—split() is a string-only function! When you try to call values.split() later, Python throws an error because it can't use a string method on a numeric type.

The Corrected Code #

Here's how to adjust your code to convert integer codes to their corresponding characters successfully:

# Capture input as a string first (don't convert to int immediately)
values_input = input("Codes: ")
# Split the input string into individual code strings
separated_values = values_input.split()
# Loop through each code string, convert to int, then to a character
for code_str in separated_values:
    code = int(code_str)
    print(chr(code))

How This Works #

1. Keep input as a string: We first grab the user's input as raw text, which lets us use split() to break it into separate code parts (e.g., input "65 66 67" becomes ["65", "66", "67"]).
2. Convert each part to integer: For each string in the split list, we convert it to an integer—this is what chr() requires to turn an ASCII code into a character.
3. Generate the character: chr(code) takes the integer code and returns its matching ASCII character (e.g., chr(65) outputs "A").

Example Test Run #

If you input 65 66 67, the code will output:

A
B
C
