Solution: Number guessing game in Python
Solution in Python 2
import random hidden = random.randrange(1, 201) # print hidden guess = int(raw_input("Please enter your guess: ")) if guess == hidden: print "Hit!" elif guess < hidden: print "Your guess is too low" else: print "Your guess is too high"
The first thing is to load the random module. It has a method called randrange that can generate an integer number ina given range. In our case we wanted to have a number that can be 1 .. 200 but because of the way the Python range works we had to call the method with 201 as the ranges in Python never include the upper boundary.
the commneted out
# print hidden
is only there so if we remove the commenting, then we can see what was the hidden value and we can check if the program works as expected.
raw_input function to prompt and to read the value from the standard input. Just as in Ruby, here too the value we receive is a string. We use the int function to convert it to an integer number.
Once we have the guess we can compare it to the hidden number and provide feedback to the user.
Solution in Python 3
import random hidden = random.randrange(1, 201) print(hidden) guess = int(input("Please enter your guess: ")) if guess == hidden: print("Hit!") elif guess < hidden: print("Your guess is too low") else: print("Your guess is too high")
There are two differences compared to the Python 2 solution:
- print() is now a function. It requires parentheses around the parameters.
- Instead of raw_input, now we should use the plain input function to get values from standard input.
