Python | Convert Bytearray to Hexadecimal String

  • Last Updated : 27 Jun, 2019

Sometimes, we might be in a problem in which we need to handle the unusual datatype conversions. One such conversion can be converting the list of bytes(bytearray) to the Hexadecimal string format. Let’s discuss certain ways in which this can be done.

Method #1 : Using format() + join()
The combination of above functions can be used to perform this particular task. The format function converts the bytes in hexadecimal format. “02” in format is used to pad required leading zeroes. The join function allows to join the hexadecimal result into a string.




# Python3 code to demonstrate working of
# Converting bytearray to hexadecimal string
# Using join() + format()
  
# initializing list 
test_list = [124, 67, 45, 11]
  
# printing original list 
print("The original string is : " + str(test_list))
  
# using join() + format()
# Converting bytearray to hexadecimal string
res = ''.join(format(x, '02x') for x in test_list)
  
# printing result 
print("The string after conversion : " + str(res))
Output :
The original string is : [124, 67, 45, 11]
The string after conversion : 7c432d0b

 

Method #2 : Using binascii.hexlify()
The inbuilt function of hexlify can be used to perform this particular task. This function is recommended for this particular conversion as it is tailormade to solve this specific problem.






# Python3 code to demonstrate working of
# Converting bytearray to hexadecimal string
# Using binascii.hexlify()
import binascii
  
# initializing list 
test_list = [124, 67, 45, 11]
  
# printing original list 
print("The original string is : " + str(test_list))
  
# using binascii.hexlify()
# Converting bytearray to hexadecimal string
res = binascii.hexlify(bytearray(test_list))
  
# printing result 
print("The string after conversion : " + str(res))
Output :
The original string is : [124, 67, 45, 11]
The string after conversion : 7c432d0b
