Hi all,
Why?
I just happened to be scrolling through my repls and happened to see this repl that I worked on for a while when I was just learning C++.
C++
DynamicSquid lol what does this line do?

how can you copyright a variable?
Also might want to use \n instead of endl since it's faster. but cool!3 years ago

I use itertools to make things easier.
How it works:
1 - Get first string
2 - Create ordered list of perm

Hi all,
I have been debating if I should learn C or C++ as one of my primary languages. I have already learned the most simple basics of each and nee
DynamicSquid C and C++ have no considerable speed difference, so that doesn't matter. I would recommend C++ though since it teaches important OOP stuff and has a larger community for resources, asking questions, tutorials, etc. Also the transition to C from C++ is way easier than the transition to C++ from C. Any questiond just ask :)3 years ago
Hi all,
I am having issues with using java scanner. The first time it is used, no issues exist. However, when I call it again, the error occurs. It h
Java
mwilki7 I would either:
• use a single scanner as a global variable, no need to close it
• pass the scanner variable as arguments to functions that also need System.in
I don't know what close() does to the System.in file descriptor so I would avoid using close() on System.in (unless avoiding it causes more problems).3 years ago
SixBeeps You don't need to make a new scanner for each time you want to take an input. I also wouldn't separate signup/login into their own classes, but that shouldn't matter.
I have a hunch that when you're making a new scanner each time, it puts a \n character, which would cause it to skip over the nextLine call.3 years ago

I don't know if you are aware of this easter egg hidden within Python. All you need to type is "import this".

I signed up for Repl.it using my Google account. However, I can't change my username. How can I change my username?

Hi all,
When you run my program and look through the css files, you might notice that the css styling does not match up with the actual result.
Addi
xxpertHacker Okay, okay, I looked at it. First, I was thrown off by your use of .form-inline input instead of input.form-inline, but otherwise your CSS is properly displaying. It appears that your problem is either your browser or your computer, not Repl.it.
Your server may be sending headers to cache the file, or you browser's just doing it, this may be your problem. That might be why you have to reload the whole computer, but I doubt it. Then again, I haven't checked the Python, nor do I know what browser3 years ago

Viper2211 Another way to do this would be like this:
import random
letters = 'a','b','c','d' #And etc.
try: lengthofpassword = eval(input("Desired Length of you Password : ")
except:import('sys').exit()
password = ""
for x in range(desired_length):
characters = str(random.randint(0,hash(random.getrandbits(128))))
character = random.choice(characters[random.randint(0,10)],random.choice(letters))
password += character

What does the ‘’ do?

Hi all,
My program keeps on giving this error:

'Create Account' Clicked

Hi all.
In my program, when the user presses the "Login" button, I want it to load the "Login.html" file and run the python function "Login()" with i
Codemonkey51 Try using multi threading
To do that one
import threading
import time
2) add time.sleep(2) as the first statement under if request.form.get('Login') == "Login": ex.
if request.form.get('Login') == "Login":
time.sleep(2)
3)make replace Login() in @app.route('/') with
t1 = threading.Thread(target=Login)
t1.start()
And you should be good (make sure after Login() executes it does not do anything else)3 years ago

JordanRenaud I'm having the exact same issue, installation just fails after the download, using other methods to install, it states that it ran out of memory or failed to allocate enough memory3 years ago
HackermonDev Its because you are an explorer. Repl.it is experimenting with a feature that moves the project out of the directory that the package is being installed. Disabling explorer should work just fine.

abc3354 Hi !
There are some problems in your code
The way you try to solve your problem is not clear
• void counter(std::string input, char character,int value) -> value is modified you need an &
void counter(std::string input, char character,int &value)
• counter doesn't work. std::find will find the first character. You need a loop
• if(capLetters[0]==want) You compare a character (want) and its occurrence in the input
I think you should use a map rather than an array
I hope this will help you ;4 years ago
