function that returns a function python

# Higher order function - function that take another function as parameter
# Function that returns a function
def mult_by(num):
    return lambda x: x * num
print("3 * 5 =", (mult_by(3)(5)))   #(5) is the parameter for the lambda fxn returned by mult_by()
# 3 * 5 = 15

# Pass a function to a function

mult_by_4 = mult_by(4)

return function in python

# Here we define the function with a parameter
# At the return statement, function ends execution
# And return the value or result of the code block
def greet(lang):
    if lang == 'spanish':
        return('Hola!')
    elif lang == 'french':
        return('Bonjour!')
    else:
        return('Hello!')

# Now we can call the function and print the returning value
print(greet('spanish'), 'Lucia.') # Output - Hola! Lucia.
print(greet('french'), 'Emma.') # Output - Bonjour! Emma.
print(greet('english'), 'James.')# Output - Hello! James.
