Python | Convert Bytearray to Hexadecimal String

Method # 1: Using format () + join ()
A combination of the above functions can be used to accomplish this particular task. The formatting function converts the bytes to hexadecimal format. "02" in the format is used to fill in the required leading zeros. The join function allows you to concatenate a hexadecimal result into a string.

# Python3 code to demonstrate how it works # Convert bytearray to hex string # Using join () + format ()   # initializing list test_list = [ 124 , 67 , 45 , 11 ]   # print original list pr int ( "The original string is:" + str (test_list))   # using join () + format () # Convert bytearray to hex string res = ’ ’.join (format (x,’ 02x ’) for x in test_list)   # print 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 built-in hexlify function can be used to accomplish this specific task. This feature is recommended for this particular transformation because it is specifically designed to address this particular problem.

# Python3 code to demonstrate how it works # Convert bytearray to hex string # Using binascii.hexlify () import binascii   # initializing list test_list = [ 124 , 67 , 45 , 11 ]   # print original list print ( "The original string is:" + str (test_list))    # using binascii.hexlify () # Convert bytearray to hex string res = binascii.hexlify (bytearray (test_list) )   # print result print ( "The string after conversion:" + str (res))

Output:

 The original string is: [124, 67, 45, 11] The string after conversion: 7c432d0b
