๐ Make It Pythonic
A function is easier to read when the invalid cases are handled first.
Instead of writing:
def create_account(email, password):
if email:
if password:
print("Account created successfully")
else:
print("Password is required")
else:
print("Email is required")
โจ Write it the Pythonic way:
def create_account(email, password):
if not email:
print("Email is required")
return
if not password:
print("Password is required")
return
print("Account created successfully")
These are called guard clauses.
They deal with invalid input before the main action begins.
Catch the invalid case first, so the main logic stays simple. ๐
