Convert an integer to an octal string using Python's oct() function

Use Python's oct() function to convert an integer to an octal string

In Python, we can use the built-in function oct() to convert an integer to the corresponding octal string. This is very practical in some specific application scenarios, such as when performing hexadecimal conversion, encoding, etc.

The syntax of the oct() function is as follows:
oct(number)

where number represents the integer to be converted.

Below, let us use a few examples to show how to use the oct() function to convert an integer to an octal string.

Example 1: Convert an integer to an octal string

# 假设我们要将整数15转换为八进制字符串
number = 15
oct_string = oct(number)
print(oct_string)

The running result is:

0o17

We can see that the octal string returned by the function starts with "0o" , followed by the corresponding octal number. In this example, the decimal number 15 is converted to the octal number 17.

Example 2: Convert an octal string to an integer

# 假设我们有一个八进制字符串"0o17"，我们要将其转换为整数
oct_string = "0o17"
number = int(oct_string, 8)
print(number)

The running result is:

15

In this example, we use the built-in function int() to convert an octal string to an integer. "0o17" is converted to the integer 15. In the int() function, we specified the second parameter as 8, which means that the string is to be parsed into an octal number.

Example 3: Convert multiple integers to octal strings

# 假设我们有一个整数列表，我们要将列表中的每个整数都转换为八进制字符串
numbers = [10, 20, 30, 40]
oct_strings = [oct(num) for num in numbers]
print(oct_strings)

The running result is:

['0o12', '0o24', '0o36', '0o50']

In this example, we use a list comprehension to convert a list of integers Each element in is converted to the corresponding octal string. Finally, we have a list of four octal strings.

To sum up, by using Python's oct() function, we can easily convert an integer into the corresponding octal string. This is very practical when performing operations such as base conversion and encoding. Hope this article helps you!
