# Let's try it!
Try executing the code below to verify the result:

a = [1, 2, 3, 4] 
a[1:2] = [10, 20, 30] 
print(a)

# Explanation

Python’s slicing operator is half-open, which is represented as `[` in math. This means we’ll get from the first index all the way up to but not including the last index. For example, `a[1:2]` is in size `1`, yet we assign a list of size `3` to it.

The Python documentation on assignments has a reputation of being a bit hard to read. But, in short, writing `a[1:2] = [10, 20, 30]` is the same as writing `a = a[:1] + [10, 20, 30] + a[2:]`.


Let’s learn about the concept of slicing in Python.
