This is still inside the loop. You want to remove the
indentation so this only happens after you exit the loop.
Otherwise you tell the user the answer before they guess
it (or have 5 goes) and it doesn't work right if the
first guess is correct...
input("\n\nPress the enter key to exit.")
You need the if/else to look like this.

Hi Danny
Thanks for your response,
I think it is part of the problem, but my intention was to end the
first loop only after 5 tries.
I don't understand why the code go to the print section after only two
gusses and not five. and it also reveal the_number before the game
end.
Again thank for your help.

This block of code appears to be applied for every iteration through
your loop. Is that your intention?

[Tutor] Help with guess my number game
Hi,I am new into Python, and using the bookPython Programming for the Absolute Beginner by Michael Dawson.One of the taks in chapte 3 is to change the "guess my number game" to include only 5 gusses and give appropriate messege at the end (in case no sucssesful guess was done).I have tried to add break for the loop after the variable "tries>5". however it seems that the program gets out from the loop after only 2 gusses. could someone give the reson or the solution to this issue.The cose is attached below:# Guess My Number## The computer picks a random number between 1 and 100# The player tries to guess it and the computer lets# the player know if the guess is too high, too low# or right on the moneyimport random print("\tWelcome to 'Guess My Number'!")print("\nI'm thinking of a number between 1 and 100.")print("Try to guess it in as few attempts as possible.\n")# set the initial valuesthe_number = random.randint(1, 100)guess = int(input("Take a guess: "))tries = 1# guessing loopwhile guess != the_number: if guess > the_number: print("Lower...") else: print("Higher...") guess = int(input("Take a guess: ")) tries += 1 if tries > 5: break if guess != the_number: print ("you failed, the number was", the_number) elif guess==the_number: print("You guessed it!

Use difflib to compare I don't see what the included code had to do with the problem, since difflib doesn’t care about numbers. It compares sequences (like lists) of strings. So you have a couple of files to read in. Normally you might use readlines, but there don't seem to be any newlines in the files. So you'll need split, or something similar. Come back when you've made an attempt at the problem, and ask a question about your code. Otherwise you're just asking others to do your homework for you. That's no way to learn. And please post in plain text.

[Tutor] Compare two text files
Hi Alan,
Attached are the two text files (stocklist.txt & stocklist1.txt) which I
want to do a comparison with the content of the file, Basically, I want to
see if there are any new numbers added to the file.
Please comment on the sequence of the file:
1. First, Open up the File No. 1 and put the string into a list.
2. Second, Open the File No. 2 and put the string into a list.
3. Use difflib to compare
This is some of the code I had written.
#Remove ".HK" from the stock list
def remove_HK():
f = open('stock_list.txt', "r")
output = open('stock_lista.txt', "w")
output.write(f.read().replace(".hk","").replace(".HK",""))
f.close()
output.close()
remove_HK()
My thinking is first remove ".HK" so I could compare in as int to another
text file.
Thank you
Henry
