python sort a list of tuples

my_list =[("p",23),("m",2),("q",19),("f",77),("a",50),]
# we will use the 'sort' method
my_list.sort(reverse = True, key = lambda t: t[1])
# the result will be
my_list
[('f', 77), ('a', 50), ('p', 23), ('q', 19), ('m', 2)]

how to sort tuples in list python

items =[

    ("product2", 2),
    ("product3", 5)
]

def value(item):     #the function return only the numbers
    return item[1]
  
items.sort(key=value)  #don't call the function but passing it
print(items)


#OR by using Lamda Function

items.sort(key= lambda item: item[1])

# Output >>> [('product2', 2), ('product3', 5), ('product1', 10)]
