Python程序给出了内部错误：_select未定义

#Start creating a "pseudo-shell"... to give the users a good feeling.

#Always good to have whitespace

#Declare variables

print "Creating computer profile in memory...\nPlease wait."#More pseudo-shells...
time.sleep(12.9384587)#Here, we start the slowdown notification.
print "Done.\nI noticed your computer setup has not been approved to be fast. You may experience slowdowns in this program."#Make sure they think you made a bulky program... it'll come in handy with delays.

rnd_seed = ( random.randint(1,1000) * random.randint(1,1000) + 2463) #Integrity check... so we know they are not manipulating RAM.
rnd_seed_bak = rnd_seed #This makes 2 variables, one for generating, one for integrity check.
print rnd_seed + "\nPlease write down this number. You may need it if your PC hangs. You have 10 seconds to write it down."#Security check. Make 'em write!
time.sleep(10)#Stay true to your word.

print "How many numbers would you like generated...?\n"
user_num = hex(int(input("Input in Decimal:")))
gen_ceiling = hex(int(input("What is the ceiling in decimal?")))
gen_floor = hex(int(input("What is the floor in decimal?")))

Why does this give me "Internal Error: _select is undefined"? I have never had that error before... it confuses me! I have tried 3 different sites, several python versions... I can't find out why it does this!

Answer 1

The only problem in your code is trying to concat an int to a string:

 rnd_seed + "\nPlease write down this number. You may need it if your PC hangs. You have 10 seconds to write it down.")  # Security check. Make 'em write!

You need to cast as a string:

str(rnd_seed) + ...

You should also be using raw_input not input for python2:

 gen_ceiling = hex(int(raw_input("What is the ceiling in decimal?")))

In python you don't have to declare variables so you can remove:

gen_out = 0 #For generator output
user_num = 0 #Declare variable before input! It goes faster.
gen_floor = 0 #For declaring minimum... once again a prompt.

and just assign the variables to the output from hex(int(raw_input...

The error is a known bug with repl, a far as your system python goes it must have somehow gotten compiled for a different platform.
