Answer : ['1', '1.0', 'a', '0.1', '-1']
Solution and Explanation:
list1 = ["1.0", "a", "0.1", "1", "-1"]

This line creates a list named list1 and assigns it the values ["1.0", "a", "0.1", "1", "-1"].

list2 = sorted(list1, key=lambda x: float(x) if x.isdigit() else float('inf'))

This line creates a list named list2 and assigns it the sorted values of list1. The key argument specifies that the sorting should be done by converting the elements to floats if they are digits, and otherwise using the value float('inf'). This means that the strings "-1", "a", and "0.1" will be sorted as if they were the numbers -1, inf, and 0.1, respectively.

print(list2)

This line prints the value of list2 to the console.

Here is a table that summarizes the steps involved in sorting the list:

Step Action

1 Create a list named list1 and assign it the values ["1.0", "a", "0.1", "1", "-1"].

2 Create a list named list2 and assign it the sorted values of list1.

3 Sort list2 using the key argument, which specifies that the sorting should be done by converting the elements to floats if they are digits, and otherwise using the value float('inf').

4 Print the value of list2 to the console.
