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

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

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

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"
