You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...

we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif. Theelifor else if statement looks like theifstatement and will evaluate another condition...
What's the recommended operator to check if a string contains a substring?Show/Hide How can you generalize a substring check to ignore case sensitivity?Show/Hide You now know how to pick the most idiomatic approach when you’re working with substrings in Python. Keep using the most descriptiv...
The Python any() and all() functions evaluate the items in a list to see which are true. The any() method returns true if any of the list items are true, and the all() function returns true if all the list items are true. Often, when you’re programming, you may want to check...
How to build Naive Bayes models in Python? Putting the theory behind, let’s build some models in Python. We will start with Gaussian before we make our way to categorical and Bernoulli. But first, let’s import data and libraries. ...
Press Enter to find the total. Method 7 – Using the AVERAGEIF Function with the If Greater Than Operator We want to evaluate the average of those averages which are higher than 80. Steps: In cell E13, insert the following formula to find the conditional average. =AVERAGEIF(C5:C11,">80...
Although using loops when writing Python code isn’t necessarily a bad design pattern, using extraneous loops can be inefficient and costly. Let’s explore some tools that can help us eliminate the…
