Pseudocode

Pseudocode means ‘mock’ or ‘pretend’ code and that it is way of describing/writing a program without using a specific programming language.

Pseudocode uses control structures and keywords similar to those found in programming languages.
Example of psedocode is:

SET name TO ‘dude’

How would this look in Python?
You need to be able to understand and use pseudocode but not write programs using it.

Python code example:

for a in range(0, 10):
    print (a)

The pseudocode for the above code is

FOR a FROM 0 TO 10
  SEND 0 to 10 TO DISPLAY
END FOR

Pseudocode:

hunger is set to N
WHILE hunger does not = Y DO
  RECEIVE hunger FROM (STRING) KEYBOARD and SEND ‘Are you hungry yet’ TO DISPLAY
SEND ‘So eat!’ TO DISPLAY
END WHILE

Python code:

hunger = "N"
while hunger != "Y":
    hunger = input("Are you hungry yet??")
print("so eat!")

Pseudocode challenge 

​What does this pseudocode do?

RECEIVE myName FROM (STRING) KEYBOARD
RECEIVE myAge FROM (INTEGER) KEYBOARD
SET AgeInTen TOmyAge + 10
SEND myName “will be” AgeInTen “in 10 years’ time” TO DISPLAY

Write the Python code for this program.
