Python is a popular object-oriented programming language. It can develop software, websites, games, and mobile applications.
“How to sort with Lambda in Python” is a fairly common question every programmer will face. So, what are our alternatives? Everything will be made clear to you.
How to sort with Lambda in Python?
Python provides the sorted() and sort() functions to sort a list.
These functions allow us to order the list by sorting it. We can sort the list in either descending or ascending order by default.
We may use one parameter in these functions, which is the key parameter. It enables us to design our sorting order. We can use lambda functions to create our single-line function in this parameter.
In addition, the easiest way is that you can use the sorted. You can sort in this manner by using lambda. Let’s take a look at an example:
mylist = ['date01', 'date10', 'date02', 'date12', 'date03', 'date13'] var1 = sorted(mylist, key=lambda x: int(x[4:])) print(var1)
['date01', 'date02', 'date03', 'date10', 'date12', 'date13']
To sort, we use lambda in the preceding example. In this example, we tell lambda to ignore the first four characters of the list to sort, which are ‘date.’ and sort by the number of the list contained within it As shown in the preceding example.
In the preceding example, we have a list of IDs, each of which is preceded by the letters id. We specify a lambda function in the key parameter that tells us to ignore the first two characters (id) and sort the list.
There are additional ways we can use lambda functions for sorting. As an example,
lst = [('Mark',1),('Jack',5),('Jake',7),('Sam',3)] lst_sorted = sorted(lst, key=lambda x: x) print(lst_sorted)
[('Mark', 1), ('Sam', 3), ('Jack', 5), ('Jake', 7)]
We have a list of tuples in the preceding example. The tuple is made up of a name and a number. In the Lambda function, we tell the function to sort the tuple based on the second element, which is the number.
Python is well suited to high-level systems. Nonetheless, performance would be marginally inferior to native language performance. However, you quickly gain safety, range of motion, and maintenance.
Individual solutions provided by these tools are some of the most fundamental for anyone confronted with the problem “How To Sort With Lambda In Python“.
