Multi-line statements

  Python interpreter can execute are called statements.

   we can make a statement extend over multiple lines with the line continuation character (\)

Python Indentation

   Most of the programming languages like C, C++, Java use braces { } to define a block of code.

Python uses indentation.

   The amount of indentation is up to you, but it must be consistent throughout that block.

   Generally four white spaces are used for indentation and is preferred over tabs.

Python comments

   Comments are very important while writing a program.

   In Python, we use the hash (#) symbol to start writing a comment.

#line continuation character (\)
a = 10 + 20 + 30 + \
40 + 50 + 60 + \
70 + 80 + 90
print(a)

#explicit line continuation using (), [] and {}
b = (10 + 20 + 30 +
40 + 50 + 60 +
70 + 80 + 90)
fruits=[‘Apple’,’banana’,’orange’]
print(b)
print(fruits)

#multiple statements in single line using (;)
c=50;d=55;e=60;
print(c,d,e)

#Python indentation example(sum of digits)
#marked area is a block of code
n=int(input(“Enter the number:”))
rev=0
while(n>0):
r=n%10
rev=rev+r
n=n//10
print(“sum of given number is:”,rev)
