Python Code Example: Convert Decimal to Octal Number

This Python code defines a function decToOct() that converts a decimal (base-10) number to its octal (base-8) representation, omitting the ‘0o’ prefix. The function takes an integer x as input, converts it to an octal string using the oct() function, then splits this string at ‘o’ and returns the last part of the split array, which is the octal value without the prefix. The print statement calls this function with the argument 125, and prints the octal representation of 125, which is 175.

Detailed Breakdown:

• Function Definition: decToOct(x) converts a decimal number x to an octal string.
• Conversion Process: Uses oct(x) to generate the octal string, then employs split('o') to discard the '0o' prefix.
• Output: Prints the octal equivalent of 125 as 175.

Code Example

def decToOct(x):
    return oct(x).split('o')[-1]

print(decToOct(125))

Output

175

Code Explanation

The function uses the built-in oct function in Python to convert x to its octal representation, represented as a string with the prefix ‘0o’. The split method is used to remove the prefix ‘0o’, and the result is returned from the function.

For example, when this function is called with the argument 125, it returns the string ‘175’, which is the octal representation of 125. The print function is used to print the result.
