Blocks and statements in Python

December 23, 2020

Block and Statement

Block : A block is a piece of Python program text that is executed as a unit. The following are blocks: a module, a function body, and a class definition. Each command typed interactively is a block. 

Statement : Instructions that a Python interpreter can execute are called statements. 

Example : 

  • def add(a,b):
    • #Block 
  • P=’PrepInsta’ #statement

Block :

  • A Python program is constructed from code blocks.
  •  A script file (a file given as standard input to the interpreter or specified as a command line argument to the interpreter) is a code block. 

Statement :

  • There are different types of statements in the Python programming language like Assignment statement, Conditional statement, Looping statements etc. 
    • P=’PrepInsta’ #assignment statement
  • Multi-Line Statements: In Python we can make a statement extend over multiple lines using braces {}, parentheses (), square brackets [], semi-colon (;),  and continuation character slash (\).
