Python Coding challenge - Day 256 | What is the output of the following Python Code?

 

Explanation:

def greet(name="Guest"):

def: This keyword is used to define a function.

greet: This is the name of the function.

name="Guest": This is a parameter with a default value. If the caller of the function does not provide an argument, name will default to the string "Guest".

 return f"Hello, {name}!"

return: This keyword specifies the value the function will output when it is called.

f"Hello, {name}!": This is a formatted string (f-string) that inserts the value of the name variable into the string. For example, if name is "John", the output will be "Hello, John!".

print(greet())

greet(): The function is called without any arguments. Since no argument is provided, the default value "Guest" is used for name.

print(): This prints the result of the greet() function call, which in this case is "Hello, Guest!".

print(greet("John"))

greet("John"): The function is called with the argument "John". This value overrides the default value of "Guest".

print(): This prints the result of the greet("John") function call, which is "Hello, John!".

Output:

Hello, Guest!

Hello, John!
