TypeError: unhashable type: 'slice' in Python A TypeError is raised in Python when we try to perform some unsupported operation on a given data type. A TypeError can also be raised while slicing if we try to use this technique on unsupported data types like a dictionary, DataFrame, and mor...
How to Use sorted() and .sort() in Python In this quiz, you'll test your understanding of sorting in Python using sorted() and .sort(). You'll revisit how to sort various types of data in different data structures, customize the order, and work with two different ways of sorting ...
range() in Python2 creates a list to iterate through, which can take up a lot of memory depending on the size. range() in Python3 is like xrange() in Python2. It creates a generator to iterate over, meaning it takes up space in memory as you step through it, not all at once. ...
mind that each character is case-sensitive. If we want to search for all the letters in a string regardless of case, we can use thestr.lower()method to convert the string to all lower-case first. You can read more about this method in “An Introduction to String Methods in Python 3....
They are the only way I know of to write into scalar NumPy ndarrays. The sentence of ellipsis slicing is not a hidden feature of python, it is just a constant. The only point is at no built-in method or Python language constructor makes use of this....
Functional programming is a programming paradigm in which the primary method of computation is the evaluation of pure functions. Even though Python isn’t primarily a functional language, you can still write Python following functional programming principles. To do this, it’s a good idea to be ...
How to Reverse a List in Python This section will cover what I think are two of the most popular techniques for reversing a list in Python: thereverse()method and list slicing. Both methods are simple and provide unique benefits depending on your use case. These are the same two methods ...
For this purpose, we will usenumpy.arr.take()method which takes indices and axis as a parameter that can be assigned in order to slice the array dynamically. Let us understand with the help of an example, Python code to slice a numpy array along a dynamically specified axis ...
This way we can use the+ operatorto concatenate multiple lists in Python. Method 2: Python concatenate multiple lists using the += operator The+=operatorin Python can be used to concatenate multiple lists in place without creating a new list. It extends the first Python list with elements fro...
