小端序str → 大端序str

一般是为了打印日志自己看着方便

  1. def Little2Big(strLittle):
  2.     lenStr = len(strLittle)
  3.     time = int(lenStr/2)
  4.     j = 0
  5.     strBig = ''
  7.     for i in range(time):
  8.         str = strLittle[lenStr-2-j : lenStr-j]
  9.         j += 2
  10.         strBig += str
  11.     return strBig
  1. def Little2Big(strLittle):
  2.     strBig = (int(strLittle, 16).to_bytes(4, 'little')).hex()[:6].upper()
  3.     return strBig
  1. import binascii
  3. def Little2Big(strLittle):
  4.     return int(strLittle, 16).to_bytes(4, 'little')
  6. def Bytes2Int(dataBytes):
  7.     return binascii.b2a_hex(dataBytes).decode()
  9. strLittle = '01020304'
  10. bytesBig = Little2Big(strLittle)
  11. strBig = Bytes2Int(bytesBig)
  13. print(strBig, type(strBig))

str → int

  1. import binascii
  3. def Little2Big(strLittle):
  4.     return int(strLittle, 16).to_bytes(4, 'little')
  6. def Bytes2Int(dataBytes):
  7.     return int((binascii.b2a_hex(dataBytes).decode()), 16)
  9. strLittle = '01020304'
  10. bytesBig = Little2Big(strLittle)
  11. intBig = Bytes2Int(bytesBig)
  13. print(intBig, type(intBig))
