) the correct answer and fill in the blank.
Ans. Integers are the whole numbers consisting of + or – sign like 75, –22, 0, 9000.
We can print out an integer in a simple way like this:
print(-25)
Output
-25
Ans. Data type defines type values and the operators that can be done with the data value. The data values we work with can be numbers or fixed. Python identifies the difference between values based on their data type.
Ans.
Multiline strings can be created by adding a backslash () at the end of the line before pressing enter or by using triple quotation marks (single or double). This will tell the compiler to continue to the next line till the ending quotation mark.
Example:
a= ‘Hello there’
print (a)
b=”Hello there”
print (b)
c=”’Hello there’”
print (c)
d=” Hello \
there \
I love python”
print (d)
Ans. A computer is an electronic machine that performs its tasks by accepting commands and instructions from the user. We need a programming languages so that we can communicate with the computer.
Ans. Variables are the named memory location created in the main memory of computer, used to store data. During the program execution these locations are created and identified by the name given by the user. With the help of these given names, values are stored, used, processed and manipulated to produce the desired results.
Rules for Naming variables:
● Variable names should be meaningful so that they are easy to remember too.
● Can be of any size
● Can have characters a-z, A-Z, 0-9 and underscore(_)
● Should begin with a letter or underscore
● Should not be a keyword
● Are case sensitive .e.g. ‘total’ and ‘TOTAL’ are not same.
Ans. Keyword are reserved words that are predefined in programming language. Variables are the named memory location created in the main memory of computer, used to store data. During the program execution these locations are created and identified by the name given by the user. With the help of these given names, values are stored, used, processed and manipulated to produce the desired results.. Each keyword has a specific function.
keywords cannot be used keyword variable.
Keyword Variable
int name
char value
Ans. Features of Python
● Python is easy to learn and use. It is developer-friendly and high level programming language.
● Python language is more expressive. That means it is more understandable and readable than other programming languages.
● Python is an interpreted language, i.e. the code is executed line by line at a time. This makes debugging easy and is thus, suitable for beginners.
● Python is portable and can run equally on different platforms such as Windows, Linux, Unix or Mac.
● Python language is freely available from its official web address – https://www.python.org. It is open source, so anyone can make changes in the source code freely.
● Python supports object-oriented languages, and concepts of classes and objects.
● It is extensible. Other languages such as C or C++ can be used to compile the Python code.
● Python has a large library that provides a rich set of module and functions for rapid application development.
● Graphical user interfaces can be developed using Python.
● It can be easily integrated with languages like C, C++, JAVA, etc.
