Python Syntax

Introduction

In this Chapter, you will learn about Python syntax. Python programming language is similar to C and C++. Python is not exactly similar but the concept is same and syntax of Python is little different from C and C++.

Now, we execute our program in an interactive mode. It is very simple, just type your Python statement and press Enter. Here, we print a message on the screen “c# corner”, we print the message, using print() function.

Syntax of print () function

print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)
 
It prints the values to a stream or to sys.stdout by default.

Optional keyword arguments are,
  • file a file-like object (stream); defaults to the current sys.stdout.
  • sep string inserted between the values, default is a space.
  • End string appended after the last value, default is a newline.
  • Flush whether to forcibly flush the stream or not.
Print(“c# corner”) on stream(screen) in an interactive mode, as shown in the picture , given below.

 

Python first program

To write our first Python program, we just do addition of two numbers in Python by following the steps, given below-

Step 1

Open Python IDLE Python 3.5.1
 
 
Press (Ctrl+N) and new file opens.
 
 

File is ready and now we have written our program in this file.

Step 2

Python code is written below.
  1. a=3  
  2. b=5  
  3. c=a+b  
  4. print("sum of a & b is:",c)  
 
Step 3

Save and run the program.
 
Press (Ctrl+Shift+S) to save our program on the location.
 
 
Click save button...

Step 4

Run the program and check the output. Press F5 to run the program.
