Python - Input & Output Operations

Input from Command Line

user_input = input("Enter the value to save in the variable:")
print("Output is:", user_input)

• Changing the data types:

  user_input1 = int(input("Enter the number 1:"))
  user_input2 = int(input("Enter the number 2:"))
  sum = user_input1 + user_input2
  print("Sum is", sum)
  

Input from a storage/file

1. File Operations

   fileobj = open(filename, mode)
   fileobj.close()
   

   • Modes:
     • r : read
     • w : write, create if file does not exist and overwrite if it exists
     • x : write only if file does not exist
     • a : append
   • Second letter of mode:
     • t : text
     • b : binary

• Example:

    fileobj = open("example.txt", "wt")
    fileobj.write("The is the content of the text file")
    fileobj.close()
