Basic for Python Programming: Syntax
Python consists of indentation, comments, variables, loops, etc Let us understand the syntax of Python in this article.
1. Indentation in Python
Python uses indentation using table or four spaces from to classify loops, classes, functions, etc. In Python, wrong indentation can lead to syntax errors.
| Basic for Python Programming |
| //Using indentation in conditional statement
if x >6: print (“The given value satisfies.”) else: print(“The given value do not satisfy.”) |
2. Variables in Python
In Python, we do not need to explicitly declare the data type of a variable. We only need to type the name and value, which automatically pick up the data type of the value stored inside the variable. In Python, variables are case sensitive and consist of letters, numbers, and underscores. Remember, you cannot start Python with a number.
| Basic for Python Programming |
| x = 6 //Here x is integer
name = pwskills // Here x is string |
3. Data Types in Python
There are different types of data types in Python, such as integer, float, dictionary, list, tuple, string, float, etc.
4. Functions in Python
Functions in Python are defined using ‘def’ keyword. Functions are made to execute a specific task and are reusable, which eliminates the need to write same line of code again and again. Let us understand with a given example.
| Basic for Python Programming |
| //function to return factorial of a number
def factorial (n): if n == 0: return 1 else: return factorial (n-1) * n |
Basic for Python Programming Language: Classes and Objects
Python consists of classes and objects, which are used to define attributes and behaviours of all objects inside the class. In Python, classes are created using ‘class’ keyword. We can create many objects as per our needs within the same class.
| Basic for Python Programming |
| class Person: // class in python
def __init__(self, name, age): //Always executed during a function call self.name = name self.age = age def myfunc(self): print(“Hello my name is ” + self.name) p1 = Person(“ABC”, 30) p1.myfunc() //creating object |
The __init__() function in Python is automatically called when a class is used.
The __str__() function returns a string value when the object is a string. We will learn more about Python classes and objects in our next tutorials.
Basic for Python Programming: Operators
In Python there are various operators such as arithmetic, assingment, bitwise, etc. Let us know about them in the table below.
| Basic for Python Programming: Operators | |
| Arithmetic Operator in Python | |
| Operator | Description |
| +(Addition) | It is used to add two or more values. |
| -(Subtraction) | It is used to subtract two or more values. |
| *(Multiplication) | It is used to perform multiplication of two or more values on either side of the operator. |
| /(Division) | It is used to divide the left hand operator by right hand operator |
| %(Modulus) | It returns the remainder when the left-hand operator is divided with the right-hand operator. |
| Assignment Operator in Python | |
| = | It takes a right-side operand and assigns its value to the left operand. |
| += | It continues to apply the right operator to the left operand and assigning the result obtained to the left operand. |
| -= | It takes away the right-hand operand from the left-hand operator and provides the value to the left operator. |
| *= | It is used to multiply the value in the right hand to the left hand operand. |
| /= | It takes the division of the two operands and then assigns the result to the left operand. |
| %= | It takes the modules and assigns the remainder value to the left-hand operand. |
| ^= | It is used to compute exponential values and assign the results to the operand on the left. |
| Identity operator in Python | |
| is | It will return true if two variables or objects refer to the same memory location. |
| is not | If two variables or objects do not point to the same memory location, it returns true. |
| Relational Operators in Python | |
| == | It validates whether the left-hand and right-hand operands are equal. |
| != | It validates whether the left-hand and right-hand operands are not equal. |
| > | If the value of the left operand is greater than the right hand operand, then it returns true. |
| < | It will return true if the given value on the left is less than the value on the right. |
| >= | It indicates that the left side value is greater or equal to the right-hand side. |
| <= | It means the left value is smaller or equal to the right-hand side. |
| Logical Operators in Python | |
| and | It will only return true if both operands are true. |
| or | It will only return true if any of the operands on either side are true. |
| not | It will return true only when both operands are false. It negates the value of a variable. |
| Bitwise Operator in Python | |
| & | Bitwise AND |
| | | Bitwise OR |
| ^ | Bitwise XOR |
| ~ | Bitwise NOT |
| << | Left Shift |
| >> | Right Shift |
Basic for Python Programming: Loops
Python supports loops to help execute a block of code repeatedly. The two main types of loops in Python programming are for and while loops.
1. For loop in Python
In Python, for loop is used to iterate over elements in tuples, list etc in a sequential manner. The syntax of Python loops is given in the table below. Check the example below.
| Basic for Python Programming |
| animals = [“cow”, “dog”, “goat”, “cat”]
for i in animals: print (i) //Output cow dog goat cat |
2. While loop in Python
These loops are used to execute a block of code repeatedly until a given condition is true. The basic syntax of the while loop is given in the table below with the help of an example.
| Basic for Python Programming |
| //Example of while loop
count = 0 while count<5: print (count) count+=1 //Output 0 1 2 3 4 |

What is a keyword in Python?
Keywords in Python are reserved words that are used for specific purposes. It cannot be declared independently and is only meant to fulfil a specific purpose. ‘def’ keyword in Python is used to declare a function and nothing else. It can't be used independently.
