(py tricks:👍) Need only write 2 lines make a simple calculator in python.

#write this code in code playground. x=eval(input('enter= ') print(x) #if user input is 2<3 #output=False #if user input is 45/5 #output = 9 #if user input is 200+2 #output=202 #if user input is 12+4/4 #output=4 #if user input is 12.4-12.2 #output=0.2 you can do anything with it.this makes python more great. THIS IS THE MAGIC OF EVAL FUNCTION.

beware that improper handling of eval may result in huge security holes.

you could also do this with a single-liner like this print(eval(input()))

Nice, but I think you are missing the last closing bracket on the first line

All you are doing is using an abstracted function. Means what you are doing is not ACTUALLY a one-liner. It is just calling another multi-liner function which is predefined.
