Python 2.4 - Points to remember

 

Points to remember

·         A Python program file is always saved with “.py” extension.

·         Python programs can be written in either interactive mode or script mode.

·         Interactive mode should be used only for practise.

·         Script mode should be used to write actual Python programs.

·         Python’s command line window and Python’s IDLE window can be used as interactive mode. Python’s IDLE window and any Text Editor can be used as script mode.

·         I recommend Python’s IDLE window to write programs for new learners.

·         Python has a very vast library used to develop variety of applications.

·         Python is an open source programming language and can be downloaded freely from python.org website.

·         Python programs can be executed in three ways – from Python command line, from Python IDLE window and from the system command prompt.

·         Since Python is an open source language, we can modify the code developed by Python development team and use it as our requirements.

·         ‘pip’ is a program that is used to download Python libraries. We can use ‘pip’ command in system prompt as shown here – pip install <package name>

·         Command ‘python’ to execute Python programs in system prompt contains both the Compiler and PVM.

·         We can download any Python libraries to develop variety of applications.

  •  numpy, pandas, xlrd, matplotlib etc. are some of the popular Python packages.

Python 4.4 - Points to remember

  Points to remember ·          Operators are symbols used to perform some operations on operands. For example, in statement z=x+y, ‘+’ and ‘=’ are operators and ‘x’, ‘y’ and ‘z’ are operands. Addition operator is used here to add two operands ‘x’ and ‘y’ and assignment ‘=’ operator is used to assign the result of addition to operand ‘z’. ·          Operators which operate upon single operand are called Unary operators such as unary ‘+’ and unary ‘-’. For example, -5, -6.8 ·          Operators which operate upon two operands are called Binary operators such as addition, subtraction etc. For example, 5+7, 45-23, x+y, x/y ·          Arithmetic operators perform mathematical calculations such as addition, subtraction, multiplication, division. Modulus, floor division and exponentiation. ·          Assignment operator ‘=’ is used to assign a value to the left side variable. ·          There are compound assignment operators such as ‘+=’, ‘-=’, ‘*=’, ‘/=’, ‘//=’, ‘%=’ and ‘**=’

Python 3.6 - Points to remember

  Points to remember ·          A variable is any location in the computer’s memory which holds a value. ·          Python is memory efficient when dealing with variables as compared to other programming languages. ·          An identifier is a name given to a variable, function, class, list, tuple etc. Identifiers are used to identify things in Python. ·          Keywords are reserved words in Python that have some special meaning and they can only be used for pre-defined purpose. ·          Comments are always used to describe the features of a program and ignored by Python compiler and interpreter. ·          ‘#’ symbol is used to create a single line comment.    ·          Python does not recommend Triple double quotes (“””) or triple single quotes (‘’’) as multi line comment. ·          If triple double quotes (“””) or triple single quotes (‘’’) are written as the first statement of a class, function, module etc., then they are called Docstrings and can be used t

Python 3.3 - Datatypes in Python

Image
  Datatypes in Python As we have already discussed that data type refers to the type of data. So datatype implies that what type of data we can store in our Python program. There are two categories of datatypes available in Python – Built-in data types and User defined data types Built-in data types The data types which are pre-defined in Python are called built-in data types. These data types have already been developed by Python developer team which we can use directly. So we do not need to do anything in it. Following are built-in data types – ·          None ·          Numbers ·          Boolean ·          Sequences ·          Sets ·          Dictionary   These datatypes are further classified in some more datatypes. Observe the image below – 1.    The None Type The None Type represents no value. When we have no value to store in a variable or object then we can store None into that variable. There might be a case when we will need a value in a variable late
