In Python, a function can return multiple values by simply separating them with commas in the return statement. Here’s an example:
def get_data():
name = "John"
age = 30
city = "New York"
return name, age, city
# Calling the function and unpacking the returned values
person_name, person_age, person_city = get_data()
print("Name:", person_name)
print("Age:", person_age)
print("City:", person_city)
Here, the get_data() function returns three values: name, age, and city. When the function is called and its return value is assigned to three variables (person_name, person_age, person_city), Python automatically unpacks the returned tuple into these variables.
In Python, a function can return multiple values by packing them into a tuple, list, or dictionary. Here are a few examples:
Returning a Tuple:
def multiple_values():
# Some computations
a = 10
b = 20
c = 30
return a, b, c
result = multiple_values()
print(result) # Output: (10, 20, 30)
Returning a List:
def multiple_values():
# Some computations
a = 10
b = 20
c = 30
return [a, b, c]
result = multiple_values()
print(result) # Output: [10, 20, 30]
Returning a Dictionary:
def multiple_values():
# Some computations
a = 10
b = 20
c = 30
return {'a': a, 'b': b, 'c': c}
result = multiple_values()
print(result) # Output: {'a': 10, 'b': 20, 'c': 30}
You can then unpack these values when calling the function:
a, b, c = multiple_values()
print(a, b, c) # Output: 10 20 30
This allows you to effectively return multiple values from a function in Python.
