Introduction to Python functions: functions and examples of the chr function

Overview:
In Python, the chr function is one of the built-in functions. It accepts an integer parameter and returns the corresponding Unicode character.

Function:
The main function of the chr function is to return the corresponding character based on the given Unicode code point. Unicode is an international standard for character encodings representing various character sets. The chr function converts Unicode code points into corresponding characters.

Syntax:
chr(i)

Parameters:
i: The Unicode code point to be converted must be an integer between 0 and 1,114,111 (including 0 and 1,114,111 ).

Return value:
Returns a string representing the character corresponding to the given Unicode code point.

Examples:
Let’s learn how to use the chr function through some specific examples.

Example 1:

print(chr(65))  # 输出结果：A

In this example, we call the chr function with the number 65 as a parameter, representing the character corresponding to Unicode code point 65. Since 65 represents the Unicode code point of the English capital letter 'A', the chr function returns the character 'A'.

Example 2:

print(chr(8364))  # 输出结果：€

In this example, we use the integer 8364 as a parameter to call the chr function, which represents the character corresponding to the Unicode code point 8364. The character corresponding to this code point is the euro symbol '€', so the chr function returns the character '€'.

Example 3:

print(chr(1234))  # 输出结果：Ӓ

In this example, we use the integer 1234 as a parameter to call the chr function, representing the character corresponding to the Unicode code point 1234. The character corresponding to this code point is a specific letter 'å', so the chr function returns the character 'å'.

Conclusion:
The chr function is a very useful function in Python, which can convert Unicode code points into corresponding characters. By rationally using the chr function, we can better handle character encoding issues in Python programming. I hope this article will be helpful in understanding the function and usage of the chr function, so that you can better use the chr function in the programming process.
