int() function in Python is used to convert a number or a string that represents a number into an integer. It removes any decimal part and returns the integer value.

To use the int() function in Python

you can simply write int() followed by the number or string that you want to convert into an integer. For example:

```

num_str = "10"

num_int = int(num_str)

print(num_int)

```

This will output:

```

10

```

If you try to convert a string that cannot be converted into an integer using the int() function

you will get a ValueError. For example:

```

num_str = "abc"

num_int = int(num_str)

```

This will raise a ValueError.

You can also convert floating-point numbers to integers using the int() function. The function will truncate the decimal part of the number. For example:

```

float_num = 10.5

int_num = int(float_num)

print(int_num)

```

This will output:

```

10

```

If you want to convert a binary

octal

or hexadecimal number to an integer

you can use the int() function with the base argument. The base argument specifies the base of the number. For example

to convert a binary number to an integer:

```

binary_num = "1010"

int_num = int(binary_num

2)

print(int_num)

```

This will output:

```

10

```

Similarly

you can convert an octal or hexadecimal number to an integer by specifying the base as 8 or 16

respectively.

In conclusion

the int() function in Python is a versatile function that allows you to convert numbers or strings representing numbers into integers. It is a useful tool for data manipulation and mathematical operations in Python programming.
