indentation matters

Indent in Python codingBlock of codes are maintained by using same indent. Line of codes within a particular loop or if condition is maintained within the same indent. Nested loops also maintain the similar indenting condition.

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
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

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)
Python adds one line break 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)

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"
