What is Algorithms and its Characteristics with examples

Algorithm:-

• An algorithm is a finite lists of instructions in sequence to solve the computation problems.
• An algorithm is a step by step of finite number of process to solve the problems.You can write the algorithms in any language which is understandable to the persons (programmers)
• In Real life,an algorithm is a recipe for any cooking dish.

Characteristics of Algorithms:-

There are following characteristics of any algorithms as given below.

string concepts in python part 5

There are some operational functions for the strings as given below:-

1.) split() :-The split() function is used to split(breaks up) at a specified separator and returns a list of strings. 

Syntax

string.split(separator,maxsplit)

The split function takes maximum two parameters as given below:-

• Separator:-This is an optional parameter.If separator is specified ,the string split at this specified separator.If separator is not specified ,the string is split at white space (space,newline,coma etc.) separator.
• maxsplit:-This is also an optional parameter.The maxsplit is used to define maximum number of splits. The default value of max split is -1 ,means no limit of number of splits.

String concepts in python Part 4

There are some search and replace functions operations in strings as given below:-
1.) find():- The find() function returns the index value of the string where the substring is found between start index and end index.start index and end index is optional parameter.

• If substring is present in given string then this function returns the index of the first occurrence of the substring.
• If the substring is not exist inside the string then it returns -1 index

String operations in python:
There are many Built-in string function available in python language.Here We will learn content test functions with examples as given below:-
1.) isalpha() :-It returns True ,if all characters in the string are alphabets otherwise False. The alphabets can be lower case and upper case both.This function doesn't take any parameters.If string contains a white space or any numeric value then this function returns False.
Syntax:-
String.isalpha()

Strings Concepts in Python Part 2

String operators in Python:-There are some operators used to perform some basic operations on strings.

• + (plus) operator) :-it is known as concatenation operator.it is used to concatenate two or more strings in python language.

e.g.

str1="Welcome to"
str2="MNT LAB"
str3="msdotnet"
str=str1+str2
print("Concatenate the two string: ",str)
print("Concatenate the two string: ",str1+' '+str3)

Output of Above Python program
Concatenate the two string:  Welcome toMNT LAB
Concatenate the two string:  Welcome to msdotnet

Strings concepts in python part 1

What is Python strings?

• Python string is a collection of Unicode characters.
• String is a popular data type of python language.
• Python allow us to create the string by using single quotes,double quotes or triple quotes.
• Strings can be created by enclosing the the character or the sequence of characters in the quotes(single,double or triple ) in python language.

We can create a string in python in following way as given below:-

Operators in Python with examples

Operators are special symbols in python which are responsible for a particular operation between two or more operands.Operators are more helpful for doing operations between two operands.We will learn everything about different type of operators in python with examples.
e.g.

a=5;b=6;
c=a+b
print("value of a+b= ",c)

Output of above program:-

value of a+b= 11
Descriptions:- In above program
operators --> =,+
operands --> a,b,c
There are many variety of operators present in python as follows:-

1. Arithmetic operators
2. Comparison operators
3. Assignment operators
4. Logical operators
5. Bitwise operators
6. Membership operators
7. Identity operators
