Python提供了内置的函数来进行ASCII码和字符之间的转换。下面是一些常用的函数：

## chr()函数

chr()函数用于将ASCII码转换为对应的字符。它接受一个整数作为参数，返回对应的字符。

`python

num = 65

char = chr(num)

print(char) # 输出'A'

## ord()函数
ord()函数用于将字符转换为对应的ASCII码。它接受一个字符作为参数，返回对应的整数值。
`python
char = 'A'
num = ord(char)
print(num)  # 输出65

## 示例：将字符串中的字符转换为对应的ASCII码

`python

string = "Hello, World!"

for char in string:

num = ord(char)

print(f"The ASCII code of {char} is {num}")

输出结果：

The ASCII code of H is 72

The ASCII code of e is 101

The ASCII code of l is 108

The ASCII code of l is 108

The ASCII code of o is 111

The ASCII code of , is 44

The ASCII code of is 32

The ASCII code of W is 87

The ASCII code of o is 111

The ASCII code of r is 114

The ASCII code of l is 108

The ASCII code of d is 100

The ASCII code of ! is 33

## 示例：将ASCII码转换为对应的字符并拼接成字符串
`python
nums = [72, 101, 108, 108, 111, 44, 32, 87, 111, 114, 108, 100, 33]
string = ""
for num in nums:
    char = chr(num)
    string += char
print(string)  # 输出"Hello, World!"

希望以上内容能够帮助你理解如何在Python中进行ASCII码和字符之间的转换。如果你有任何其他问题，请随时提问！
