将 ASCII 转换为二进制的Python程序
在本文中，我们将讨论Python编程语言中 ASCII 到二进制的转换。
方法一：使用binascii模块
Binascii 有助于在二进制和各种 ASCII 编码的二进制表示之间进行转换。
a2b_uu()函数：这里的“uu”代表“UNIX 到 UNIX 编码”，它负责根据指定的程序将数据从字符串转换为二进制和 ASCII 值。 a2b_uu()函数用于将指定的 ASCII 格式转换为其对应的二进制等效格式。
Syntax: a2b_uu(Text)
Parameter: This function accepts a single parameter which is illustrated below:
- Text: This is the specified ASCII string that is going to be converted into its binary equivalent.
Return Values: This function returns the binary equivalent.
示例：使用Python将 ASCII 转换为二进制
Python3
# Python program to illustrate the
# conversion of ASCII to Binary
# Importing binascii module
import binascii
# Initializing a ASCII string
Text = "21T9'(&ES(&$@0U,@4&]R=&%L"
# Calling the a2b_uu() function to
# Convert the ascii string to binary
Binary = binascii.a2b_uu(Text)
# Getting the Binary value
print(Binary)Python3
# Python program to illustrate the
# conversion of ASCII to Binary
# Calling string.encode() function to
# turn the specified string into an array
# of bytes
byte_array = "GFG".encode()
# Converting the byte_array into a binary
# integer
binary_int = int.from_bytes(byte_array, "big")
# Converting binary_int to a string of
# binary characters
binary_string = bin(binary_int)
# Getting the converted binary characters
print(binary_string)输出：
b'GFG is a CS Portal'方法 2：使用内置类型
首先调用字符串.encode()函数将指定的字符串转换为字节数组，然后调用int.from_bytes(byte_array, byte_order) 以byte_order 为“big”，将byte_array 转换为二进制整数。最后，调用斌（binary_int）到binary_int转换成二进制字符的字符串。

# turn the specified string into an array
# of bytes
byte_array = "GFG".encode()
# Converting the byte_array into a binary
# integer
binary_int = int.from_bytes(byte_array, "big")
# Converting binary_int to a string of
# binary characters
binary_string = bin(binary_int)
# Getting the converted binary characters
print(binary_string)
输出：
