Getting started
To getting started, install python and create a py file
# This is a comment. comments are ignored by the interpreter
# Declare a variable
hello = "hello world"
# It allows you to define multiple variables in one line
a, b, c = 1, 2, 3
# Print the variable
print(hello)# Define a function
def say_hello(time):
# If statements
if time < 12:
print("Good morning!")
else:
print("Good evening!")
# Python also allow you to use a anonymous function called lambda
# This lambda takes two arguments and returns the sum of them
sum = lambda a, b: a + b
result = sum(1, 2)
print(result)
# Will print 3
say_hello(result)
# Will print "Good morning!"Python also support creation of classes and object that will allows you to use Object Oriented Programming.
# Create class Cat
class Cat():
# Create constructor
def __init__(self, name, age):
super().__init__(name)
self.age = age
# Create method
def __str__(self):
return f"{self.name} is {self.age} years old"
# Create object
cat = Cat("Garfield", 10)
# Print object
print(cat)
# Will print "Garfield is 10 years old"Run the py file
