int() Function in Python

Python int() Function

The int() function in Python is used to convert a given value to an integer. It can take different types of input and convert them into integers based on specific rules. Here's the general syntax of the int() function:

int(x, base=10)

The int() function takes two arguments:

1. x (required): The value to be converted to an integer. It can be a string, float, boolean, or another integer.
2. base (optional): The base in which the input value is represented. It can be an integer between 2 and 36. If not specified, the default value is 10.

Here are a few examples to illustrate the usage of the int() function:

# Converting a string to an integer
num_str = "42"
num_int = int(num_str)
print(num_int)  # Output: 42

# Converting a float to an integer
num_float = 3.14
num_int = int(num_float)
print(num_int)  # Output: 3

# Converting a boolean to an integer
bool_val = True
bool_int = int(bool_val)
print(bool_int)  # Output: 1

# Converting an integer from a different base (binary)
binary_str = "10101"
binary_int = int(binary_str, base=2)
print(binary_int)  # Output: 21

In the last example, the int() function is used to convert a binary string representation of a number to an integer. By providing base=2, we specify that the input string is in base 2 (binary), and the resulting integer will be the decimal equivalent.
