'[0] * 10' in Python

In Python, the expression '[0] * 10' creates a new list that consists of 10 elements, all of which are 0. This is a very useful feature for initializing arrays or lists to a specific size or value.

Syntax

The syntax of '[0] * 10' is as follows:

[0] * 10

This will create a new list with 10 elements, all of which are 0.

Example Code

Here is an example Python program that uses the '[0] * 10' syntax:

# Initialize a list of 10 zeros
my_list = [0] * 10

# Print the list
print(my_list)

Output:

[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

Explanation

In the example code above, we first create a new list called 'my_list' and initialize it with 10 zeros using the '[0] * 10' syntax.

We then print the contents of 'my_list', which should be a list of 10 zeros.

Conclusion

The '[0] * 10' syntax in Python is a very powerful tool for initializing arrays or lists to a specific size or value. It can save you a lot of time and effort, especially when dealing with large arrays or lists that would be difficult to initialize manually.
