Use “Ctrl+F” to find any questions answered. For mobile users, you just need to click on three dots in your browser, and you will get a “Find” option there. Use these options to get any random question answered.

Getting Started with Python

  • Python requires that you specify the type of variable before it being assigned.
  • Python supports both functional and object oriented programming.
  • Python does not require a type for a variable declaration. It automatically assigns the data type at run time.
  • Python requires you to explicitly set the correct data type and value before assigning a variable.
  • A block is created using a colon following by a new line and indentation
  • A block is created by a new line
  • A block is created using a semi colon and a new line
  • A block is created using a semi colon and indentation
  • The remove keyword
  • The def keyword
  • The del keyword
  • A variable cannot be deleted
  • It controls the flow of the loop and stops the current loop from executing any further.
  • The break statement will suspend the code until continue is run.
  • To terminate the code
  • The break keywork is used to debug a for loop.

a = isinstance(str, "aa")


  • It will throw an error.
  • “aa”
  • False
  • True
  • input("")
  • "" = input("My name is: " + name)
