x+=5 if x+5<10 else 0
In this above example i should add 5 to x if x+5 is less than 10.
but as you can see i am calculating x+5 two times how can i do without repeating it.
like
"add x to 5 if it doesnt become greater than 10 after adding"
is this possible on python? if yes then how do you do that?
From Python 3.8, there is the new "walrus" operator. :=, which allows assignments as expressions, just like the = operator behaves in C like languages.
You can rewrite your expression as:
x = y if (y:= x + 5) < 10 else x
Well you could convert this expression:
x + 5 < 10
into this:
x < 5
Then rephrase your if else one liner as:
x += 5 if x < 5 else 0
# We know x+=5 is same as x = x + 5
# for the conditional x + 5 < 10 is rewritten as x < 5
# We define a range for x.
for x in range (10):
x = x + 5
print(x)
if x<5 :
print(x)
else:
x=0
x? Does it have to use a conditional expression? What actually is the question here?
