First Program in Python

First Program

• It is terribly easy to put in writing and execute any Python Program.
• Python Program may be executed directly within the command.

print("Hello Python")

• 
  

Indentation in Python

• C ,C++,Java etc. languages use braces to point blocks of code for sophistication and performance definitions or flow management.
• But Python uses indentation to point a block of code.
• We can use a minimum of one space for indentation.
• indentation could be a important component in Python as a result of if you forget or skip the indentation then you may get a error in program.

Program: Greatest value in two number

a=5
b=10
if a>b:
    print("a is greater than b")
else:
    print("b is greater than a")

• Python code will raise an error if you skip indentation.

a=5
b=10
if a>b:
#this line will raise an error
#because no indentation
print("a is greater than b")
else:
    print("b is greater than a")
"""
***Output***
Indentation Error: expected an indented block
"""

• You can use range of areas for indentation however areas should be same within the same block of code.

a=5
b=10
if a>b:
         print("a is greater than b")
         print("means b is less than a")
else:
         print("b is greater than a")
         print("means a is less than b")
"""
***Output***
b is greater than a
means a is less than b
"""
