python中怎么将整数转换为二进制或十六进制字符串？

decimal_number = 255

# 转换为二进制字符串
binary_string = bin(decimal_number)
print(f"The binary representation of {decimal_number} is: {binary_string}") # 输出: The binary representation of 255 is: 0b11111111

# 转换为十六进制字符串
hexadecimal_string = hex(decimal_number)
print(f"The hexadecimal representation of {decimal_number} is: {hexadecimal_string}") # 输出: The hexadecimal representation of 255 is: 0xff

# 去掉前缀 "0b" 或 "0x"
binary_string_no_prefix = binary_string[2:]
hexadecimal_string_no_prefix = hexadecimal_string[2:]

print(f"Binary without prefix: {binary_string_no_prefix}") # 输出: Binary without prefix: 11111111
print(f"Hexadecimal without prefix: {hexadecimal_string_no_prefix}") # 输出: Hexadecimal without prefix: ff

format()

decimal_number = 10

# 使用 format() 方法，指定宽度为 8，填充 0
binary_string_formatted = format(decimal_number, '08b')
print(f"Formatted binary: {binary_string_formatted}") # 输出: Formatted binary: 00001010

hex_string_formatted = format(decimal_number, '02X') # 大写十六进制，宽度为 2
print(f"Formatted hexadecimal: {hex_string_formatted}") # 输出: Formatted hexadecimal: 0A

# 使用 f-string
binary_string_fstring = f'{decimal_number:08b}'
print(f"f-string binary: {binary_string_fstring}") # 输出: f-string binary: 00001010

hex_string_fstring = f'{decimal_number:02X}'
print(f"f-string hexadecimal: {hex_string_fstring}") # 输出: f-string hexadecimal: 0A

format()

'08b'

'02X'
