How to Round number in Python

In Python, you can round a number using the built-in round() function. The round() function takes two arguments: the number you want to round and the number of decimal places to round to. Here’s an example:

num = 3.14159
rounded_num = round(num, 2)
print(rounded_num)

In this example, num is the number you want to round and 2 is the number of decimal places to round to. The output will be 3.14.

If the second argument is omitted, the round() function will round to the nearest integer:

num = 3.7
rounded_num = round(num)
print(rounded_num)

In this example, num is 3.7 and the round() function rounds it to 4.
