Hey everyone! Sorry it's been a while since our last meeting. Today, we're diving into an exciting lesson about lambda functions in Python.
Looking forward to seeing you all!

Lambda functions
Another cool expressions or patterns in python are lambda functions a.k.a anonymous functions. We use them to define functions inline (in one line).
The subtle thing we need to understand about
The concept actually exists in many programming languages as

# Syntax
lambda arguments: expresion
The subtle thing we need to understand about
anonymous funtions/lambda functions is that they don't have a name unless we explicitly assign them to a variable. The return value of lambda function is the evaluated expression.The concept actually exists in many programming languages as
anonymous functions or function expression, even-though the syntax could be different.# Examples
# This is valid - With no name
lambda x: x
# With a name
times2 = lambda x: x * 2
# With two argumetns
prefix = lambda pre, post: pre + post;
postfix = lambda post, pre: prefix(pre, post)
print(times2(10))
print(prefix("main", ".py"))
print(postfix(".py", "main"))
# ----------Output----------
