python list sort method code example

Example 1: how do i sort list in python

my_list = [9, 3, 1, 5, 88, 22, 99]

# sort in decreasing order
my_list = sorted(my_list, reverse=True) 
print(my_list)

# sort in increasing order
my_list = sorted(my_list, reverse=False) 
print(my_list)

# another way to sort using built-in methods
my_list.sort(reverse=True)  
print(my_list)

# sort again using slice indexes
print(my_list[::-1])

# Output
# [99, 88, 22, 9, 5, 3, 1]
# [1, 3, 5, 9, 22, 88, 99]
# [99, 88, 22, 9, 5, 3, 1]
# [1, 3, 5, 9, 22, 88, 99]

Example 2: python sort

>>> student_tuples = [
...     ('john', 'A', 15),
...     ('jane', 'B', 12),
...     ('dave', 'B', 10),
... ]
>>> sorted(student_tuples, key=lambda student: student[2])   # sort by age
[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]

Example 3: how to manually sort a list in python

Numbers = []
iterate = 0

while len(Numbers)<5:
    try:
        x = int(input("Insert the number you want in the list: "))
        Numbers.append(x)
    except:
        print("The input  MUST be a number.")
        continue
    for iteration_count in range(len(Numbers)):
        #This acts like a counting method
        for j in range(0,len(Numbers)-1):
            #It swaps each element for each iteration (j is just a random variable)
            if (Numbers[j]>Numbers[j+1]):
                Numbers[j],Numbers[j+1] = Numbers[j+1],Numbers[j]
print(f"Here are the sorted numbers:{Numbers}")

Example 4: sort in python'

arr = [1,4,2,7,5,6]
#sort in ascending order
arr = arr.sort() 

#sort in descending order
arr = arr.sort(reverse = True)

Example 5: python sort

nums = [4,8,5,2,1]
#1 sorted() (Returns sorted list)
sorted_nums = sorted(nums)
print(sorted_nums)#[1,2,4,5,8]
print(nums)#[4,8,5,2,1]

#2 .sort() (Changes original list)
nums.sort()
print(nums)#[1,2,4,5,8]
