First python program in python?
First Program
- It is very simple to write and execute any Python Program.
- Python Program can be executed directly in the command line .
print("Hello Python")
- C ,C++,Java etc languages use braces to indicate blocks of code for class and function definitions or flow control.
- But Python uses indentation to indicate a block of code.
- We can use at least one space for indentation.
a=5 b=10 if a>b: print("a is greter 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 lin will raise an error #because no indentation print("a is greter than b") else: print("b is greater than a") """ ***Output*** IndentationError: expected an indented block """
- You can use number of spaces for indentation but spaces must be same in the same block of code.
a=5 b=10 if a>b: print("a is greter 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 """
