48 generator in python

 

'''

1. Using generator we can execute a block of code

 based on demand by using next() function.

2. using yield keyword we can create a generator.

'''


def gen_fun(n):

    for i in range(n):

        print('Before yield')

        yield i

        print('After yield')


gen_obj = gen_fun(10)


#print(next(gen_obj))


#print(next(gen_obj))


# print(next(gen_obj))


## Iterate based on for loop

#for i in gen_obj:

#    print(' For Loop ', i)



def gen_fun(n):

        print('Before return')

        yield n

        print(' \n After return')

        yield n


gen_obj = gen_fun(10)

print(next(gen_obj))

print(next(gen_obj))

  Python Programming tutorial provides basic and advanced concepts of Python programming. This Python programming  tutorial is designed for beginners and professionals.  Python is a simple, general purpose, high level, and object-oriented programming language. In this we have different chapter and their concepts Python Programming : tokens, literals, identifiers, keywords, special symbols and operators; fundamental data types, expressions, type conversions, handling Input and output in Python. Selection Statements : if statement, if-else statement, if-elif-else statement, nested-if statement.  Iterative Statements : while loop, for loop, break statement, continue statement, pass and else statements used with loops. Sequences : Lists and operations - creating, inserting elements, updating elements, deleting elements, searching and sorting, list comprehensions, nested lists; tuples - creating, searching and sorting, nested tuples;  strings - Initializing a string and string opera

16 file handling in python

 1. Using file handling we can do file operations # How to open a file in python ? 1. We can open a file two ways in python      1. open()     2. With open() # OPEN 1. Using open we can open only one file at a time and we have to close a file explicity # WITH OPEN  1. Using with open we can open multiple files at a time and no need to close files explicity # File Open Modes In Python r    ==>     It opens a file for read only. w    ==>     It allows write-level access to a file. If the file already exists, then it’ll get overwritten. It’ll create a new file if the same doesn’t exist. a    ==>     It opens the file in append mode. a+   ==>     It opens a file FOR append AND read rb   ==>     It opens a binary file for read 1)  Read file fh = open('names.txt', 'r') ## To open a file from another path #fw = open(r'C:\Users\smellamput001\Desktop\BACKUP_EPRO\RRR.txt', 'r') ## Using read we can read entire file data and return in string format f

4 Tuple data types

 ''' 1. Tuple is used to store multiple values and  we can do operation on each value based on index. 2. Tuple is a read only object,  we can't do update,insert and delete operations. 3. Using parentheses "()" we can create a tuple 4. tuple is a immutable object 5. To store sensitive data we use tuple. ''' # To create a tuple names = ('umamahesh','kumar','balu','ram', 567, 99.9) # Tuple doesn't support for item deltion and update names[3] = 'ok' del names[3] # To print particular value based on index print(names[4]) print(names[-1]) # To delete a total tuple del names
