Python chr()函数与示例

1. chr()函数的概述

在Python中，chr()函数用于将Unicode码转换为对应的字符。该函数需要一个整数作为参数，该整数代表一个Unicode码点。

2. chr()函数的语法

chr(i)

参数说明：

• i：必需，整数，表示一个Unicode码点。

返回值说明：

• 返回对应Unicode码点的字符。

3. chr()函数的示例

下面是chr()函数的一些示例：

示例一：将Unicode码转换为字符

#将Unicode码转换为字符
unicode_num = 65
char = chr(unicode_num)
print("Code point {0} is character {1}".format(unicode_num, char))

输出结果：

Code point 65 is character A

示例二：使用循环将字符串转换为Unicode码并输出

#使用循环将字符串转换为Unicode码并输出
my_string = "abcdefghijklmnopqrstuvwxyz"
for i in range(len(my_string)):
    print("Code point {0} is character {1}".format(ord(my_string[i]), my_string[i]))

输出结果：

Code point 97 is character a
Code point 98 is character b
Code point 99 is character c
Code point 100 is character d
Code point 101 is character e
Code point 102 is character f
Code point 103 is character g
Code point 104 is character h
Code point 105 is character i
Code point 106 is character j
Code point 107 is character k
Code point 108 is character l
Code point 109 is character m
Code point 110 is character n
Code point 111 is character o
Code point 112 is character p
Code point 113 is character q
Code point 114 is character r
Code point 115 is character s
Code point 116 is character t
Code point 117 is character u
Code point 118 is character v
Code point 119 is character w
Code point 120 is character x
Code point 121 is character y
Code point 122 is character z

4. 总结

chr()函数用于将Unicode码转换为对应的字符。可以通过for循环将字符串转换为Unicode码并输出。在使用时需要注意参数的正确性。
