Learn to design, develop, and execute basic programs in Python.

Zero to Hero in Python for Data Science

This module provides a comprehensive introduction to the tools that help create various programs, such as documents, movies, and games. We'll start with a brief introduction to data science, followed by simple math, real-world problem solving, and precise writing solutions. Next, we'll learn decision-based solutions demonstrated via flowcharts and explained with execution sheets. Finally, we'll learn to translate our solutions into Python programs using variables, conditional statements, loops, strings, lists, and built-in functions. We'll also learn to create our custom functions in Python. After completing this module, we will have acquired the skills to write basic programs in Python.

Understanding Data Science with a focus on Python


# Task


Write a function that accepts two strings as parameters and checks whether these strings are anagrams of each other. An **anagram** is a text formed by rearranging the letters of another piece of text.

The strings should _not_ be case-sensitive, meaning that `Cats` and `AcTs` are anagrams.



The function should return `1` when the strings are anagrams and `-1` otherwise.


---
## Sample input 1
```t
str1 = silent
str2 = Listen
```
## The resulting return value 1
```t
1
```
## Expected output 1
```t
The strings are anagrams.
```
---
## Sample input 2
```t
str1 = accept
str2 = expect
```
## The resulting return value 2
```t
-1
```
## Expected output 2
```t
The strings are not anagrams.
```

## How to test your program

When you click the "Test" button of the code widget, you get two options, as explained below:

* **Show Results**: It shows the sample inputs and their respective results in comparison with the expected output. The actual output is the calculated return value after comparing the strings to display the results. The word "Succeeded" in the last column indicates that the calculated output matches the expected output. For example, if `str1` and `str2` are `silent` and `Listen`, respectively, and the return value of the function is `1`, then the last column shows "Succeeded". Similarly, if `str1` and `str2` are `accept` and `expect`, respectively, and the return value of the function is `-1`, then the last column again shows "Succeeded".

* **Show Console**: It shows the output from the `print()` statements used in your code. You may use this to verify your calculations on the basis of sample test inputs. For example, if `str1` and `str2` are `silent` and `Listen`, respectively, then the output on the console should be `The strings are anagrams.`. Similarly, if `str1` and `str2` are `accept` and `expect`, respectively, then the output on the console should be `The strings are not anagrams.`.

Check whether two strings are anagrams of each other.
