在Python中，我们可以使用`bin()`或`format()`将整数转换为二进制字符串表示形式。

print(bin(1))                       # 0b1
      print(bin(-1))                      # -0b1
      print(bin(10))                      # 0b1010
      print(bin(-10))                     # -0b1010
    
      print("{0:b}".format(10))           # 1010
      print("{0:#b}".format(10))          # 0b1010 , with 0b prefix
      print("{0:b}".format(10).zfill(8))  # 00001010 , pad zero, show 8 bits
    
      print(format(10, "b"))              # 1010
      print(format(10, "#b"))             # 0b1010, with 0b prefix
      print(format(10, "b").zfill(16))    # 0000000000001010, pad zero, show 16 bits
    
      # with hex, oct bin
      # int: 10;  hex: a;  oct: 12;  bin: 1010
      result = "int: {0:d};  hex: {0:x};  oct: {0:o};  bin: {0:b}".format(10)
      print(result)
    
      # with 0x, 0o, or 0b as prefix:
      # int: 10;  hex: 0xa;  oct: 0o12;  bin: 0b1010
      result = "int: {0:d};  hex: {0:#x};  oct: {0:#o};  bin: {0:#b}".format(10)
      print(result)
