Question 8

An incomplete Python program for simulating a chemical reactor's target temperature is shown in Figure 1 below.

The program should generate a random target temperature between 180 and 360 degrees Celsius (including 180 and 360). This will be the secret target temperature the user has to guess.

Figure 1

1      import random
2
3      print("Enter your guess for the target temperature (C)")
4      userTemp = int(input())
5      while userTemp < 180 or userTemp > 360:
6          print("Invalid temperature")
7          userTemp = int(input())
8      print("Valid temperature entered")
9      if targetTemp == userTemp:
10         print("Warning: Reactor core matches critical threshold!")

Write the Python code that should be used on line 2 in Figure 1 to:

  • generate a random integer between 180 and 360 inclusive
  • assign this number to the appropriate variable from the program.

You must use random.randrange(a, b) in your Python code.

Note that random.randrange(a, b) generates a random integer in the range a a\,a to bbb, starting at a a\,a but finishing one before bbb (exclusive of bbb).
