www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Python Variable C=‘edureka’ A = 16 B = 20 C = ‘edureka’ B=20 A=16 Memory Memory Memory Variable Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory.

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Data types Python Data types A data type, in programming, is a classification that specifies which type of value a variable has and what type of mathematical, relational or logical operations can be applied to it without causing an error. C=‘edureka’ A = 16 B = 20 C = ‘edureka’ B=20 A=16 Integer Datatype Integer Datatype String Datatype

Tuples are sequences, just like lists. Tup1 = ('physics', 'chemistry', 1997, 2000)For example: Accessing Values in Tuple Updating Tuple Delete Tuple Elements Tuple Length Concatenation Repetition

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING String Data type Strings Set Dictionary Numeric1 4 5 6 Lists32 Strings24 Tuples3 A string in Python is a sequence of characters. We can create Strings by enclosing characters in quotes. Python treats single quotes the same as double quotes. Consider the example below: Operation Syntax String Length print(len(string_name)) Locate a character in string print(strig_name.index(“Char")) Count the number of times a character is repeated in a string print(string_name.count("Char")) Print a part of the string print(string_name[start:stop]) Reverse a string print(string_name[::-1]) Convert the letters in a string to upper-case print(string_name.upper()) Convert the letters in a string to lower-case print(string_name.lower()) A = ‘Master Python At edureka’ B = ‘Welcome to edureka!’

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Python Operations Operators Identity Operators Membership Operators Comparison Operators Arithmetic Operators Assignment Operators Logical Operators Bitwise Operators Operations Operators are the constructs which can manipulate the value of operands.

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Arithmetic and Comparison Operators Arithmetic Comparison a + b a – b a * b a / b a % b a ** b Addition Multiplication Subtraction Division Modulus Exponent a == b a != b a > b a < b a >= b a <= b Equal To Greater Than Not Equal To Less Than Greater Than Equal To Less Than Equal To

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Assignment and identity Operator Assignment a = b a + = b a - = b a * = b a /= b a** = b Assigns value from right to left a = a - b a = a + b a = a*b a = a/b a = a**b Identity is is not Evaluates to true if the variables on either side of the operator point to the same object and false otherwise. Evaluates to false if the variables on either side of the operator point to the same object and true otherwise.

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Membership and Bitwise Operator Membership in not in Evaluates to true if it finds a variable in the specified sequence and false otherwise. Evaluates to true if it does not find a variable in the specified sequence and false otherwise. Bitwise a & b a | b a ^ b a ~ b a << a >> b Binary AND Binary OR Binary XOR Binary NOT Binary Left Shift Binary Right Shift

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Logical Operator There are three types of logical operators: Logical AND, Logical NOT, Logical OR a and b a or b Returns a if a is false, b otherwise Returns b if b is false, a otherwise not a Returns True if a is True, False otherwise

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Conditional Statements in Python If Statement Syntax: If code End Start Condition is true Condition Condition is false Exit

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Conditional Statements in Python Elif Statement If code End Start Condition is true Condition If condition is false Elif codeSyntax:

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Conditional Statements in Python Else code If code Elif condition is false If condition is true Elif code If condition is false Condition End StartElse Statement Syntax:

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Loops in Python A loop statement allows us to execute a statement or group of statements multiple times. The following diagram illustrates a loop statement:Loops Loops NestedForWhile Start Conditional Code Condition If condition is false If condition is true End

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING While Loop While Loop Repeats a statement or group of statements while a given condition is TRUE. It tests the condition before executing the loop body. Syntax: Start Conditional Code End If condition is true If condition is false Condition

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING For Loop For Loop Repeats a statement or group of statements while a given condition is TRUE. It tests the condition before executing the loop body. Syntax: Start Execute Statement (s) End Next item from sequence If no more items in the sequenceItem from sequence

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Nested Loops in Python Nested Loops Python programming language allows use of one loop inside another loop. This is called Nested Loop, below is the syntax for the same: Syntax: Syntax:

www.edureka.co/pythonEDUREKA PYTHON CERTIFICATION TRAINING Functions in Python Functions A function is a block of organized, reusable code that is used to perform a single, related action. Functions Predefined Functions User Defined Functions Function Add Call (3,5) Call (6,9) Call (1,5) Call 1 Call 2 Call 3 Return 8 Return 15 Return 6
