As far as I know, now we can declare variables using type annotation syntax in Python 3.6 as following code.
def printInt():
a: int = 0
b: int = 1
c: int = 2
print(a, b, c)
What I want to do is declaring variables a, b, c in one line.
I tried a, b, c: int, but it returns error.
Also a: int=0, b: int=1, c: int=2 returns error too.
Is there any way to declare multiple variables using type annotation syntax in one line?
If you really want to use annotation then you can do this in this form:-
a: int;b: int;c: int
a,b,c = range(3)
print(a,b,c) #As output 0 1 2
a: int = 0; b: int = 1; c: int = 2
would actually work.
If you are looking for a way to avoid repeating int all times, I am afraid you cannot as of Python 3.7.
Commas are not allowed and will yield a syntax error. You can't use the regular one liner:
a, b, c = 0, 1, 2
The workarounds would work in any python version with typing support:
a: int; b: int; c: int; a, b, c = 0, 1, 2
a: int = 0; b: int = 1; c: int = 2
It does not apply to your question but this would work too in some cases:
abc: tuple[int] = (0, 1, 2)
Python is completely object oriented, and not "statically typed". You do not need to declare variables before using them, or declare their type. Every variable in Python is an object.
a,b,c=0,1,2
Or the following maybe what you are looking for
def magic(a: str, b: str) -> int:
light = a.find(b)
return light
a, b cyou have to assign them asa,b,c=0,1,2
