raw-input

问题 This question already has answers here : How can I read inputs as numbers? (10 answers) Closed last year . I am having trouble with if statements in python. I am making a "game" entirely in dolan speak, excuse the spelling, it meant to be humorous manner. Sorry. Here is the code: import time def menu(): print ("dogz r a supar hahrd tin 2 matsr it tak yrs 2 mastr ut u nw git 2 exprince it. pik a tin 2 du:\n") menu = raw_input("1.)Ply Da Dogi gam\n2.)Halp\n") if menu == 1: game() if menu == 2:

问题 I wanted to understand the behaviour of raw_input in the below code. I know num will be string. Irrespective of whatever number i enter it always enter the elif part i.e. if num is 5, which should go to if num<check: part or if num is 10 which should go to else part. Every single time it is going to elif . I thought comparing STRING and INT might throw exception( I dont think so) but just in case, so I had included try except but as expected it did not throw any exception. But what puzzles me

问题 Say I want to use raw_input like this: code = raw_input("Please enter your three-letter code or a blank line to quit: ") under: if __name__=="__main__": How can I let it repeat multiple times rather than just once every time I run the program? Another question is to write what code can satisfy the condition "or a blank line to quit (the program)". 回答1: best: if __name__ == '__main__': while True: entered = raw_input("Please enter your three-letter code or leave a blank line to quit: ") if not

问题 In the following code i am trying to make a "more" command (unix) using python script by reading the file into a list and printing 10 lines at a time and then asking user do you want to print next 10 lines (Print More..). Problem is that raw_input is asking again and again input if i give 'y' or 'Y' as input and do not continue with the while loop and if i give any other input the while loop brakes. My code may not be best as am learning python. import sys import string lines = open('/Users

问题 I am working on a program that checks hostnames of specific sites, and I want to be able to insure that when asked for the hostname (with raw_input ) it ends in a TLD ( .com , .net , .org ). I am not exactly sure how to do this in Python. In bash I have: local TLD=(com info org net) for entry in ${TLD[@]}; do blah blah done What is the equivalent in Python? 回答1: endswith(suffix[, start[, end]]) will do the trick. Documentation Please also note that suffix can be a tuple of suffices! TLD = ('

问题 Just trying to write a program that will take the users input and add it to the list 'numbers': print "Going to test my knowledge here" print "Enter a number between 1 and 20:" i = raw_input('>> ') numbers = [] while 1 <= i <= 20 : print "Ok adding %d to numbers set: " % i numbers.append(i) print "Okay the numbers set is now: " , numbers However when I execute the program it only runs to raw_input() Going to test my knowledge here Enter a number between 1 and 20: >>> 4 Is there some

问题 Hi I'm a 11 year old who has taken up python as a hobby. I'm trying to make a mass converter as a first project. But for some reason I've been getting this error: TypeError: can't multiply sequence by non-int of type 'float' Here is my code: print "please enter the amount of kilograms you want to convert", kilo = raw_input() pounds = 2.20462 print kilo * pounds 回答1: raw_input returns a string, you're basically doing this: print "1234" * 2.20462 You need to convert the input to a number: kilo
