Basic Knowledge of Python part 1

Basic Mathematics equations using Python- As we know python is a simple and easy to learn programming language. In this section we learn how to done mathematics equations using python. To perform this we use our basic operators +,-,/,* . To perform python we have to open python interpreter. In this interpreter you can type simple equation like 5+5, 4/2 etc. For example: The integer number (e.g. 1,2,3....) have type int and the number with fractional part (e.g. 2.5,2.1,4.5...) have type float. Note:- The division type always returns float. To get only an integer result of division you can use the // operator and to get remainder from division result you can use % operator. In python you can easily calculate power of the number by using ** operator. Like this you can easily calculate mathematics equation. Now we see how to find area of rectangle. Area = length*width is the formula to find area of rectangle. Here '=' sign is used to store value to the variable. You can als...

Python | Data Structure or Data Types (String)

Data Type Of Python I n the last session we discus about what is the data type of python. And we see List data type. In this session we s ee the next data type String. 2) String- String is a ordered collection of immutable data type. String are iterable and hashable. Strings are always declared in single or double quotes. Single line string:- S = "Python" Multi line string:- S = """ Line 1 Line 2 Line 3 """ Iterable:- S= "Program" for i in S: print(i) Output:- P r o g r a m Membership:- print( 'p' in S) => True print( 'P' not in S) => False Methods of string:- capitalize() :- It return the capitalize version of the string. More specifically it make the first character have uppercase and rest lowercase. For example:- S = "hello World" print(S.capitalize()) => "Hello world" count(substring, start,en...

Python | Data Structure Or Data Type (Tuple)

Data Type Of Python In this session we will see last data type of python which is Tuple. 5) Tuple:- Tuple is a ordered collection of immutable datatype, tuples are quite similar to lists but difference is list are mutable where as tuple are immutable. Empty tuple:- t = () or tuple() Tuple with single element:- t = (10,) Tuple with multiple element:- t1 = ( 10, 20, 30, 'Hello' ) Nested tuple:- t1 = ( 10, 20, 30, 'Hello' ) p = t2, 30, 40, 50 print(p) => ((10, 20, 30, 'Hello'), 30, 40, 50) Methods of Tuple:- count(value):- It return the count of value if the value is present in the tuple else it return 0. For example:- t = (10, 20, 30, 'Hello') t.count(10) => 1 t.count(50) => 0 index(value,start,end):- It return the index number if the value is present in the tuple, otherwise it raised value error. For example:- t = (10, 20, 30, 'Hello') t.index(10) => 0 It return the index number of value 10. Prev Topic Next Topic
