Input Statements in Python: We can read the variables by using python input() function as:1) We can write any string/text to be displayed at the python prompt as an argument to the input function.2) If we don’t specify any string/text to be displayed at the python prompt , then nothing will be displayed. But we …
Type Conversion: It means to convert the operands of one data type into another data type. Types of Conversions: Python supports two types of conversions:1) Implicit Type Promotion/ Internal Conversion 2) Explicit Type Casting/ External Conversion 1) Implicit Type Promotion/ Internal Conversion : It is the conversion done by the python compiler/interpreter without user’s intervention.1) …
Expressions: It is any valid combination of operators and operands (may be literals / variables). It is composed of one or more operations. Example 1) 5 + 4 is valid2) 5 + -4 is valid3) 5 + * 6 is invalid because in this case, compiler will be confused which operation whether + or * …
Statements Flow Control: It determines the order of execution of statements in a program. Types of Statements Flow Control: There are 3 types of flow control in python.1) Sequential Flow2) Conditional / Branching / Decision Making / Selection Statements3) Iteration/ Repetition/ Looping Statements 1) Sequential Flow: In it, statements are executed in sequence one after …
Statements: It is a command or instruction that the python interpreter can understand and execute. If we type a statement on the command line, Python executes it.We may also write a sequence/group of statements in a script/program. Types of Statement: There are 3 types of statements:1) Empty Statement2) Simple Statements3) Compound Statements / Block Empty Statement: …
Indentation It refers to the (spaces and tabs) that are used at the beginning of a statement. It is used to create groups/blocks/compound statements in python.The statements with the same indentation belong to the same group/block. Block / Compound Statement It is a group of statements (piece of python program text) executed as a unit. The …
The structure of a program is defined by its control flow. It is built from blocks of code, where each block has a single entry and a single exit point in the control flow.The typical structure of a python program include 3 parts Import statements// import statements are used to include library files to the …
Precedence: It gives the order of execution of operators in an expression i.e. gives an idea about which operator is to be executed first when there are multiple operators in an expression.Example: The expression 4+3 * 2 can be solved by two ways. But only way1 is correct Way 1) 4+3 * 2=4+6 (3 * …

Operator: It is a symbol that performs some action. Python supports following types of operators: Arithmetic operators : Python supports 7 arithmetic operators1) + : To perform addition2) – : To perform subtraction3) * : To perform multiplication4) / : To perform division5) // : To perform integer division ie returns greatest integer less than …
Working of Python: In python, variables are stored as references to a value object. Each time you change the value, the variable’s reference memory address changes. Python frontloads some commonly used values in memory. Each variable referring to that value actually stores that memory address of the value. Multiple variables/identifiers can refer to a single …
