print()

print(object ,sep='Separator',end='end',file=file,flush=flush) returns output to screen or file
objectTo be printed to screen or file
sepOptional , separator can be used between the outputs
endOptional, default is '\n', used to remove line break after the output
fileOptional , file object to write to file
flushOptional , Default value is False, Managing buffer

String output

print('Hello world')

Python print() function to display output using sep end file and flush options

printing output with format

id=5
name="Ronal Jack"
mark=45
print("ID :{:02d} Name:{:15s} Mark: {:2d}".format(id,name,mark))
Output is here
ID :05 Name:Ronal Jack      Mark: 45
More on placeholder {}
str1="Welcome "
str2=" to "
str3=" Python "
str4=" Your student id = "
id=5

print(" Hi {2} {1} {0} ".format(str1,str2,str3))
print(" Hi {0} {1} ".format(str4,id))
Output is here
Hi  Python   to  Welcome  
 Hi  Your student id =  5 
Correct the first line to get proper sequnce of words

Right align

name='My Name'
age=5
print("Name  {:>25s}, Age {:2d}".format(name,age))
Now the name variable will align right ( within the 25 char space )
Name                    My Name, Age  5

Printing decimal upto 2 places using format

my_str="Mr ABCD"
avg=356.23456
id=5
name="Welcome to Python"

print("Hi {}, Your id = {}, Your Average ={:.2f})".format(my_str,id,avg))
Output is here
Hi Mr ABCD, Your id = 5, Your Average =356.23)

end

Python adds one line break ( default value of end='\n' ) after each print command, we can remove the line break ( Watch the end='' within the print ())
my_str="Mr ABCD"
avg=356.23456
id=5
name="Welcome to Python"

print("Hi {}, Your id = {} ".format(my_str,id),end='')
print("Your Average ={:.2f})".format(avg))
output is here
Hi Mr ABCD, Your id = 5 Your Average =356.23)
We can use end to print any string at the end of the output. Check here how we used end='...' to print dots after the number.
for i in range (4):
  print(i,end='...')
Output
0...1...2...3...

sep

We can add a separator in between strings
print('welcome','to','plus2net', sep='-')
Output
welcome-to-plus2net

Multiple strings with +

print('Welcome '+ 'to '+'plus2net')
Output
Welcome to plus2net

flush

We can send the output by flushing the internal buffer. Default value for flush is False.
In this case we are trying to send each output within the loop after a delay of 1 second. With the default setting of False the output will come all at the same time after a delay of 5 seconds. By keeping the value of flash=True we can send the outputs in steps with a delay of 1 second.
import time
for i in range(5,0,-1):
    print(i,end=' >> ',flush=False) # default value for flush
    #print(i,end=' >> ',flush=True) # delay in each output 
    time.sleep(1) # delay of 1 second 
print('Over')
Python print output with flush option to clear the buffer with example using timer

String and Integer

We can't print string with integer, this will generate error. TypeError: must be str, not int
print('Your visitor number is :' + 34)
We can use str() to change our integer to string.
print('Your visitor number is :' + str(34))

Write to file

with open('my_file.txt', mode='w') as fob:
    print('hello world', file=fob)
This will create my_file.txt file in same directory and write 'hello world' to it.

Printing using variables inside string

a=2
b="welcome"
c="Python"
print("Hello ",b," to ", c )
Output is here
Hello  welcome  to  Python

Using escape char

Test on Basics of Python Let us print I can't travel by bus
print(' I can\'t travel by bus')
We used escape char \ inside the word can't to print single quote instead of using as string termination.
We can use special char \ inside our string without using as escape char by adding r before the quotes
print(r"C:\MyDocument\python\test.py")
Here \t is not considered as Tab and the out put is here
C:\MyDocument\python\test.py

We can add doble quote inside single quote
print ( 'We said "Welcome to plus2net"')
Output is here
We said "Welcome to plus2net"

print() with list

More on List
my_list=['One','Two','Three'] # A list 
print(my_list) # ['One', 'Two', 'Three']

print() with tuple

More on tuple
my_list=('One','Two','Three') # A tuple 
print(my_list) # ('One', 'Two', 'Three')

print() with set

more on set
my_set={'Alex','Ronald','John'}
print(my_set)

print() with dictionary

my_dict={1:'Alex',2:'Ronald'}
print(my_dict) # {1:'Alex',2:'Ronald'}
