Programmingis pretty fun,but at some point, when you try to run the program, unfortunately, and inevitably, errors will show up. So, causing, understanding, and fixing errors is integral toprogramming.

There are three significanttypes of errors that you can get in Python,but here we will talk about how to solvePythonruntime errors.

A run-timeerrorhappens whenPythonunderstands what you are saying but runs into trouble when following your instructions.

How can I fix the Python runtime error?

How can I fix the Python runtime error?

So you’ve written everything correctly. In other words, your syntax is correct, butPythonstill doesn’t understand what you’re saying. Let’s have a simple example of aPythonruntime error:

If you try to run this simple line, you will receive a runtime error simply because you didn’t define thesolutionvariable. The line doesn’t make sense.

To understand better that conundrum, let’s make an association with English grammar. Let’s take this sentence, for instance.

Grammatically, there is absolutely no problem with this sentence. Everything is there; we have all the syntax elements correct.

But when you are trying to understand the sentence, when you piece up the words, it doesn’t make sense because you know you can open and close the door, even shut it or taking it out but eating it?

In programming, this will be called arun-time errorbecause it shows up before you start theprogram. There are a few types of runtimeerrors. In this article, you will learn how to solve them.

1. Use an undefined variable or function

This can also occur if you use capital letters inconsistently in a variable name:

callMe = “Brad”print(callme)

In this case, theprogramreturned the undefined variableerror. You defined the variablecallMe, but you tried to print another variable,callme.You must use the variables precisely as you define them, case sensitive.

2. Dividing by zero

Guess what?Pythoncares about math, and dividing by zero makes no sense in math.

print(1/0)

So this line returns a runtimeerrorasPythoncan read it properly, but when it comes to executing it, he refuses to do so as it has no mathematical sense.

3. Use operators on the wrong type of data

This line returns the runtime error because you try adding text with numbers, crayons, oranges, chairs with pigeons, etc. It just doesn’t make sense to perform operations with different types of variables.

You also need to know thatPythonruns theprogramin two steps. It first checks the syntax and if the syntax is correct, it goes to the second step of executing theprogram. That’s where he stumbles on possible runtimeerrors.

To better handle errors such as these in the future, we have a great guide on how to usetry-except-print in Pythonfor error handling.

If you are facing another issue with Python, such aspython setup.py bdist_wheel did not run successfully; we have a separate guide to how to use it.

In case you’re having problems with Python, we also have a guide on_xsrf argument missing from posterror, so feel free to check it out. Our latest guide coversCannot open shared object no such file or directoryerror, so don’t miss it.
