Use the Python List sort() method to sort a list in place. The sort() method sorts the string elements in alphabetical order and sorts the numeric elements from smallest to largest. Use the sort(reverse=True) to reverse the default sort order.
Python sorted() Function The sorted() function returns a sorted list of the specified iterable object. You can specify ascending or descending order. Strings are sorted alphabetically, and numbers are sorted numerically. Note: You cannot sort a list that contains BOTH string values AND numeric values.
 Select a single cell in the column you want to sort.
 On the Data tab, in the Sort & Filter group, click. to perform an ascending sort (from A to Z, or smallest number to largest).
 Click. to perform a descending sort (from Z to A, or largest number to smallest).
Python Program to Sort List in Ascending Order without using Sort. In this program, we are using Nested For Loop to iterate each number in a List, and sort them in ascending order. if(NumList[0] > NumList[1]) = if(67 > 86) – It means the condition is False. So, it exits from If block, and j value incremented by 1.
Use the itemgetter() Function From the Operator Module Along With the sorted() Function to Sort a List of Lists in Python. The function sorted() is used to sort a list in Python. By default, it sorts the list in ascending order.
If you want to sort in a descending order, all you have to do is add the parameter reverse = True to either the sort or sorted functions. They both accept it!
To sort a list alphabetically in Python, use the sorted() function. The sorted() method sorts the given iterable object in a specific order, which is either ascending or descending. The sorted(iterable, key=None) takes an optional key that specifies how to sort.
 Sorting on multiple columns. Pandas also make it possible to sort the dataset on multiple columns. …
 Sorting by Multiple Columns With Different Sort Orders. …
 Sorting by index. …

 Apply the key function to the values before sorting.
The ORDER BY keyword sorts the records in ascending order by default. To sort the records in descending order, use the DESC keyword.
In Python, there are two ways, sort() and sorted() , to sort lists ( list ) in ascending or descending order. If you want to sort strings ( str ) or tuples ( tuple ), use sorted() .
Solution(By Examveda Team) Sorting data in MS Excel rearranges the rows based on the contents of a particular column. We can also sort a table to put names in alphabetical order or ascending or descending order.
 STEP 1: Declare and initialize an array.
 STEP 2: Loop through the array and select an element.
 STEP 3: The inner loop will be used to compare the selected element from the outer loop with the rest of the elements of the array.
 STEP 4: If any element is less than the selected element then swap the values.
 Set a variable, lowest, to the first element in the unordered list.
 For each element in the unordered list. If the element is lower than lowest. Assign the value of that element to lowest.
 Append lowest to the ordered list.
 Remove lowest from the unordered list.
The easiest way to sort is with the sorted(list) function, which takes a list and returns a new list with those elements in sorted order. The original list is not changed. It’s most common to pass a list into the sorted() function, but in fact it can take as input any sort of iterable collection.
 Sample Solution:
 Python Code: import numpy as np x = np.arange(24).reshape((6,4)) print(“Original arrays:”) print(x) new_array = np.transpose(x) print(“After reverse the dimensions:”) print(new_array) …

To sort a twodimensional list in Python use the sort() list method, which mutates the list, or the sorted() function, which does not. Set the key parameter for both types using a lambda function and return a tuple of the columns to sort according to the required sort order.
 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)
Call pd. DataFrame. sort_values(column, ascending=False) to sort a pd. DataFrame in descending order based on the values in column .
Approach: An ArrayList can be Sorted by using the sort() method of the Collections Class in Java. This sort() method takes the collection to be sorted as the parameter and returns a Collection sorted in the Ascending Order by default.

You can sort a dataframe using the sort_values method. df. sort_values(by=[‘contig’, ‘pos’], ascending=True) # where contig and pos are the column names. So, you may change for yours.
 Sorting by a Column in Ascending Order. To use .sort_values() , you pass a single argument to the method containing the name of the column you want to sort by. …
 Changing the Sort Order. Another parameter of .sort_values() is ascending . …
 Choosing a Sorting Algorithm.
 by: Single/List of column names to sort Data Frame by.
 axis: 0 or ‘index’ for rows and 1 or ‘columns’ for Column.
 ascending: Boolean value which sorts Data frame in ascending order if True.
 inplace: Boolean value.
In order to sort the data frame in pandas, function sort_values() is used. Pandas sort_values() can sort the data frame in Ascending or Descending order.
Array elements can be sorted in descending order by passing in the array and Collections. reverseOrder() as parameters to Arrays. sort().
Arranging the array’s elements from largest to smallest is termed as sorting the array in descending order. First, sort the array using Array. Sort() method which sorts an array ascending order then, reverse it using Array. Reverse() method.
To sort an array in reverse/decreasing order, you can use the std::sort algorithm provided by STL. It sorts the elements of a container in the range pointed by the specified iterators using a comparator. The default comparator used is std::less<> , which sorts the container in ascending order using operator< .
The sort() method sorts the elements of an array in place and returns the sorted array. The default sort order is ascending, built upon converting the elements into strings, then comparing their sequences of UTF16 code units values.
To sort a Tuple in Python, use sorted() builtin function. Pass the tuple as argument to sorted() function. The function returns a list with the items of tuple sorted in ascending order. We may convert this list to tuple using tuple().
Use a lambda function as an argument to sort() to sort a list of tuples by the second value. Call list. sort(key=None) with list as a list of tuples and key set to lambda x: x[1] to sort list by the second element of each tuple.
Numbers are said to be in ascending order when they are arranged from the smallest to the largest number. E.g. 5, 9, 13, 17 and 21 are arranged in ascending order.
Definition of in ascending order : arranged in a series that begins with the least or smallest and ends with the greatest or largest The children were lined up in ascending order of height.
To quick sort in ascending order, click A to Z command in Excel that sorts A to Z or smallest number to largest (Sort A to Z). To quick sort in descending order, click Z to A command in Excel that sorts Z to A or largest number to smallest (Sort Z to A).
