Python Syntax Basics
Before we start writing python code, let’s discuss some of the basics common to all Python scripts. These include variables, data types, operators, and control flow tools.
Variables
Variables in Python are easy to declare. Unlike in other programming languages, you don’t need to specify the type of variable because Python is a type infer language.
# variable assignment var = "Hello, Zenva!" print(var)
Data Types
Python supports various data types, of which the most commonly used are str, int, float, bool, and list.
# string strVar = "Zenva" # integer intVar = 2022 # float floatVar = 3.14 # boolean boolVar = True # list listVar = [1, 2, 3, 4, 5]
Operators
Python includes a variety of operators, which are symbols that carry out arithmetic or logical operations.
# arithmetic operators print(10 + 5) print(10 - 5) print(10 * 2) print(10 / 2) # comparison operators print(10 == 10) print(10 != 5) print(10 > 5) print(10 < 20)
Control Flow
Python also offers several control flow tools, such as if/else statements, for loops, and while loops.
# if/else statement
x = 20
if x > 10:
print("x is greater than 10.")
else:
print("x is not greater than 10.")
# for loop
for i in range(5):
print(i)
# while loop
i = 0
while i < 5:
print(i)
i += 1These examples cover some of the basics you’ll need to understand as you start programming in Python. They’re just scratching the surface, however, so let’s move on to some more advanced concepts.
Python Functions
Functions in Python are blocks of reusable code that perform a specific task. They are declared with the def keyword, followed by the function name and parentheses ().
def greeting(name):
print("Hello, " + name)
greeting("Zenva")Python Classes and Objects
Python is an object-oriented programming language. You can create your own objects by defining a class, which serves as a blueprint for an object.
class Zenva:
def __init__(self):
self.course = "Python for Beginners"
def greeting(self):
print("Welcome to " + self.course + ".")
course_instance = Zenva()
course_instance.greeting()Data Structures
Python provides several types of data structures, including lists, tuples, sets, and dictionaries.
# list
listVar = ["python", "java", "c++"]
# tuple
tupleVar = ("python", "java", "c++")
# set
setVar = {"python", "java", "c++"}
# dictionary
dictVar = {
"language": "python",
"creator": "Guido van Rossum",
"year": 1991
}Exception Handling
Python uses try/except blocks to handle exceptions. This allows the program to continue running even when an error occurs.
try:
print(undefined_variable)
except:
print("An error occurred")Exception handling is a powerful tool in Python and any other programming language, as it prevents errors from ending a program prematurely.
By now, you should have a solid understanding of the basics of Python programming. Let’s keep going and explore some more advanced topics.
