You can use a return statement to return multiple values from a function. To do that, you just need to supply several return values separated by commas.For example, suppose you need to write a function that take
class Circle: all_circles = [] pi = 3.14159 def __init__(self, r=1): self.radius = r self.__class__.all_circles.append(self) def area(self): return self.__class__.pi * self.radius * self.radius @staticmethod def total_area(): total = 0 for c in Circle.all_circles: total...
Python functions can return values, which allows you to retrieve information or the result of a computation from the function. Sometimes, you may wantyour function to return a key-value pair, a common data structure used in Python dictionaries. Key-value pairs help link pieces of related inform...
To implement a similar function in Python, you could use multiple return values as you’ve seen previously: Python def tryparse(string, base=10): try: return True, int(string, base=base) except ValueError: return False, None This tryparse() returns two values. The first value indicates ...

def some_func(x): if x == 3: return ["wtf"] else: for i in range(x): yield iOutput:>>> list(some_func(3)) [] The same result, this didn't work either.💡 Explanation:From Python 3.3 onwards, it became possible to use return statement with values inside generators (See PEP...

A few action methods return values. For example, the service that manages a storage domain has an is_attached action method that checks whether the storage domain is already attached to a data center and returns a Boolean value: Copy to Clipboard Toggle word wrap # Check if the st...
