Question

solve in python

Write a function randomNumber which will return a single random integer from 0 to 9, inclusive. It does not accept any parameters.

Write a function randomLetter which will return a random (lowercase) letter of the English alphabet (hint: if you still have you code from the last quiz, you can copy some of it to use here). It does not accept any parameters.

Write a function generatePassword that will create and return an alphanumeric password. 

  • It should accept one parameter: an integer nn 
  • The function should then randomly generate nn characters, assemble them into a string, and return that string
  • Each character should have a 50% chance of being a letter and a 50% chance of being a number, and should be generated by calling one of the functions you defined earlier.
  • If it is a letter, it should have a 50% chance of being uppercase and a 50% chance of being lowercase

Hints:

  • randomNumber and randomLetter should be one or at most two lines long, not counting the definition
  • generatePassword should be around 10 lines long

Sample Output

Here is a possible result of calling print(generatePassword(10))
