Python: Convert decimal to hexadecimal

Python Basic: Exercise-141 with Solution

Write a python program to convert decimal to hexadecimal.

Sample decimal number: 30, 4
Expected output: 1e, 04

Pictorial Presentation:

Convert decimal to hexadecimal

Sample Solution-1:

Python Code:

x = 30
print(format(x, '02x'))
x = 4
print(format(x, '02x'))

Sample Output:

1e                                                                                                            
04

Sample Solution-2:

Python Code:

def dechimal_to_Hex(n):   
   x = (n % 16)
   ch = ""
   if (x < 10):
       ch = x
   if (x == 10):
       ch = "A"
   if (x == 11):
       ch = "B"
   if (x == 12):
       ch = "ch"
   if (x == 13):
       ch = "D"
   if (x == 14):
       ch = "E"
   if (x == 15):
       ch = "F"
   if (n - x != 0):
       return dechimal_to_Hex(n // 16) + str(ch)
   else:
       return str(ch)
dechimal_nums = [0, 15, 30, 55, 355, 656, 896, 1125]
print("Dechimal numbers:")
print(dechimal_nums)
print("\nHexadechimal numbers of the said dechimal numbers:")
print([dechimal_to_Hex(x) for x in dechimal_nums])

Sample Output:

Dechimal numbers:
[0, 15, 30, 55, 355, 656, 896, 1125]

Hexadechimal numbers of the said dechimal numbers:
['0', 'F', '1E', '37', '163', '290', '380', '465']

Sample Solution-3:

Python Code:

def dechimal_to_Hex(dechimal_nums):
   digits = "0123456789ABCDEF"
   x = (dechimal_nums % 16)
   rest_part = dechimal_nums // 16
   if (rest_part == 0):
       return digits[x]
   return dechimal_to_Hex(rest_part) + digits[x]
dechimal_nums = [0, 15, 30, 55, 355, 656, 896, 1125]
print("Dechimal numbers:")
print(dechimal_nums)
print("\nHexadechimal numbers of the said dechimal numbers:")
print([dechimal_to_Hex(x) for x in dechimal_nums])

Sample Output:

Dechimal numbers:
[0, 15, 30, 55, 355, 656, 896, 1125]

Hexadechimal numbers of the said dechimal numbers:
['0', 'F', '1E', '37', '163', '290', '380', '465']
