Introduction to Python functions: functions and examples of oct function

Python is a powerful programming language with many built-in functions to handle various tasks. One of the very useful functions is the oct() function.

The oct() function is used to convert an integer to an octal string. It accepts an integer as argument and returns an octal string representing the integer.

The following is the syntax of the oct() function:

oct(number)

Among them, number is the integer that needs to be converted.

Let's look at some examples to understand the functionality of the oct() function.

Example 1:

# 将整数8转换为八进制字符串
print(oct(8))

# 输出结果
0o10

In the above example, we pass the integer 8 to the oct() function. The oct() function converts 8 to the octal string "0o10" and returns it.

Example 2:

# 将整数123转换为八进制字符串
print(oct(123))

# 输出结果
0o173

In this example, we pass the integer 123 to the oct() function. The oct() function converts 123 to the octal string "0o173" and returns it.

Example 3:

# 将整数-10转换为八进制字符串
print(oct(-10))

# 输出结果
-0o12

In this example, we pass the negative integer -10 to the oct() function. The oct() function converts it to the octal string "-0o12" and returns it. Note that the octal representation of negative numbers begins with "-0o".

Use the oct() function to conveniently convert integers to octal strings. This is very useful in some specific programming scenarios, especially when dealing with base conversions and bit operations.

In addition to the oct() function, Python also provides some other similar built-in functions, such as the bin() function for converting integers to binary strings, and the hex() function for converting integers to hexadecimal strings. hexadecimal string.

To summarize, the oct() function is a very useful built-in function in Python for converting integers into octal strings. Its syntax is simple and clear, and its functions are powerful. By using the oct() function, we can easily perform base conversion operations in Python programs.
