Split a string
Hello all, I have a simple question.
How would I see if first the word Jump is in the string and then see if the word Up is one space after it. Then how could I split the string into two parts ("Jump " and "Up") to use the "Up" string for later use? Thanks :)
x.split()will give you each word as an element in a list. So, to get the second word of your sentence, you use
You could do something like:
words = x.split() if words.lower() == "jump": second_word = x.split()
It works fine, but when I tried to make a different little project with it, an error I can't understand the cause of keeps popping up:
from objc_util import * import console UIScreen = ObjCClass('UIScreen') screen = UIScreen.mainScreen() x=input() words=x.split() if words.lower() == "set": second_word = x.split() float(second_word) screen.setBrightness_(second_word)
For this little project, I just want to be able to input some text and check if it says set and has a decimal number (like 0.9) after it. Then I want to convert that 0.9 to a float to be used to set the screen brightness to 0.9. When I tell it to run and type in exactly what's necessary, nothing happens. What could I be doing wrong?
floattakes a string, tries to convert it to a float number, and returns that number if successful. If you write
second_wordto a float number, and then throws it away, because you aren't storing the returned value anywhere. You need to write something like
brightness = float(second_word) screen.setBrightness_(brightness)
float(second_word)is never stored hence,
screen.setBrightness_(second_word)will fail as a
strobject is being passed as an argument instead of a
float_value = float(second_word)and changing
screen.setBrightness_should resolve your issue.
I agree that
objc_utilerrors can sometimes be a little hard to read, however the error type (
ValueError, etc) can be a hint towards what the issue might be. In this instance passing a
