convert a number from base 10 to base 16 in python

To convert a number from base 10 to base 16 in Python, we can use the built-in hex() function.

The hex() function takes an integer as its argument and returns a string representing the hexadecimal value of that integer. Here's an example:

main.py
num = 255
hex_num = hex(num)

print(hex_num)
45 chars
5 lines

Output:

main.py
0xff
5 chars
2 lines

In the example above, we first define a variable num and set it to the decimal value 255. We then call the hex() function with num as its argument and assign the resulting hexadecimal value to a new variable hex_num. Finally, we print out the value of hex_num.

Note that the hex() function returns a string, so if you need to perform any arithmetic operations on the resulting value, you will need to convert it back to an integer using the int() function:

main.py
hex_num = '0xff'
decimal_num = int(hex_num, 16)

print(decimal_num)
68 chars
5 lines

Output:

main.py
255
4 chars
2 lines

In the example above, we first define a variable hex_num and set it to the string value '0xff'. We then call the int() function with hex_num as its first argument and 16 as its second argument to specify that the input string is in base 16. We assign the resulting integer value to a new variable decimal_num and print out its value.
