Hello, I found strange the use of ‘print “”’, when in Python3 it should be ‘print()’. Also, I never saw this ‘{}’ in Python3 nor the ‘.format()’ method.

Can someone explain me what is all this? Have I passed to Python2 suddenly without knowing? Why is not ‘print(“whatever " + value + " continue the text if you want to”)’? I mean, what’s the point on using the brackets and ‘.format()’ method? How did they make the print work without calling it as a function?

Thank you
