python sort tuples code example

Example 1: pyhon sort a list of tuples

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda x: x[1])

Example 2: sort by tuple

sorted_by_second = sorted(data, key=lambda tup: tup[1])

Example 3: pyhon sort a list of tuples

# Python program to sort a list of tuples by the second Item 
  
# Function to sort the list of tuples by its second item 
def Sort_Tuple(tup):
    # Getting length of list of tuples
    lst = len(tup)
    for i in range(0, lst):
        for j in range(0, lst-i-1):
            if (tup[j][1] > tup[j + 1][1]):
                temp = tup[j]
                tup[j]= tup[j + 1]
                tup[j + 1]= temp
    return tup

Example 4: how to sort tuples in python

# If you have a tuple, first convert it to a list:

a = (3,1,2)
a = list(a)

# And now you can just use the inbuilt function ( .sort() ):
a.sort()
print(a)
>>> [1,2,3]

# ^ by using .sort() you are modifying the original list / tuple, however
# if you want to make a sorted copy of the list / tuple, then you use this:

a = [3, 6, 8, 2, 78, 1, 23, 45, 9]
print(sorted(a))

>>> [1, 2, 3, 6, 8, 9, 23, 45, 78]

# This also works with the alphabet or a combination between letters and
# numbers.
