UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)

This error occurs when you try to encode a string that contains non-ASCII characters using the ASCII codec. The ASCII codec can only handle characters in the range of 0-127, so any characters outside of that range will cause this error.

To fix this error, you need to encode the string using a codec that supports the characters you're trying to use. Some examples of codecs that support a wider range of characters include UTF-8, UTF-16, and ISO-8859-1.

Here's an example of how to encode a string using the UTF-8 codec:

my_string = "Hello, 世界!"
encoded_string = my_string.encode('utf-8')

In this example, the `encode()` method takes an argument that specifies the codec to use for encoding. We're using the UTF-8 codec, which supports a wide range of characters including the Chinese characters in the string.
