In this tutorial, we will learn about Python functions, categories of functions like module functions, built-in & user-defined functions, what they are, and their usages with the help of examples. By Abhishek Jain Last updated : December 30, 2023 ...
If you simply want to import a module (potentially within a package) by name, you can call __import__() and then look it up in sys.modules: >>> import sys >>> name = 'foo.bar.baz' >>> __import__(name) >>> baz = sys.modules[name] >>> baz input([prompt]) If the ...
Pythonlists can store an ordered collection of items, or elements, of varying types. They are often used to compile multiple items into a single, mutable variable, which is helpful for retrieving items, specifying outputs or performing calculations quickly. Lists are also a type of built-indata...
In Python, we have various special numbers that turn out to be floats: +/-infinity(inf),nan. In the section above, we saw infinite and learned what they represent. We also have thenan, commonly known as “Not a Number” but as ironic as it may seem,nanis a floating point number. I...

To signal when the iteration must stop, you must raise the StopIteration exception in the .__next__() method. Note: To learn more about iterators in Python, check out the Iterators and Iterables in Python: Run Efficient Iterations tutorial. To illustrate how to use StopIteration, say that ...
In Python, thetype()function can be used to get the data type of any object. Let us see an example. x=5print(type(x))# <class 'int'>y='howtodoinjava.com'print(type(y))# <class 'str'> 11. Conclusion The above-discussed Python data types provide the building blocks for more co...
Python Copy In this example, wecreated a pandas DataFrameswith an index of integers. By usingdf.reset_index(), we reset the index back to the default integer index. The old index doesn’t disappear; it’s moved into a new column named ‘index’. ...
Next, we need to divide the dataset into a training set and a test set. In the field of EEG analysis, commonly used data partitioning methods include k-fold cross-validation and leave-one-out cross-validation. In this tutorial, we use k-fold cross-validation on the entire dataset (KFold...
