NameError: Name plot_cases_simple Is Not Defined error is a generic name error. This plot cases simple is just a placeholder.
This can be the name of a function, a variable, or a Python module. In this article, we’ll show you how to fix this error by giving plot cases simple as a dummy name.
What is NameError: Name plot_cases_simple Is Not Defined?
In Python, the NameError happens when you try to use a variable, function, or module that doesn’t exist or wasn’t used in a valid way.
Some of The Common Mistakes That Cause This Error are:
- Using a variable or function name that is yet to be defined.
- Misspelling a variable/function name when calling the variable/function.
- Using a Python module without importing the module, and so on.
How To Solve NameError: Name plot_cases_simple Is Not Defined?
In this section, you will learn how to fix the Python error “NameError: Name is Not Defined.” I’ve split this section into sub-sections to show the error above when using variables, functions, and modules.
- Example 1 – Variable Name Is Not Defined in Python
- Example 2 – Function Name Is Not Defined in Python
- Example 3 – Using a Module Without Importing the Module Error in Python
Example 1: Variable Name Is Not Defined in Python
name = "Jude" print(age) # This will be the Output: #NameError: name 'age' is not defined
In the code above, we set up a variable called “name,” but we tried to print “age,” which hasn’t been set up yet.
We got an error that says: NameError: name ‘age’ is not defined. This means that the age variable doesn’t exist.
Example 1 Solution:
We can fix this by making the variable, and then our code will run correctly. Here’s an example of code:
name = "Jude" age = 26 print(age) # This will be the Output: # 26
Example 2: Function Name Is Not Defined in Python
def sayHi(): print("Hi IT SOURCECODE!") sayHello() # NameError: name 'sayHello' is not defined
In the above example, we used sayHello() instead of sayHi() to call the function ().
We got this error: NameError: name’sayHello’ is not defined. It’s easy to miss spelling mistakes like this. Most of the time, the error message will help you fix this.
Example 2 Solution:
def sayHi(): print("Hi IT SOURCECODE!") sayHi() # This will be the output: # Hi IT SOURCECODE!
Example 3 : Using a Module Without Importing the Module Error in Python
x = 5.5 print(math.ceil(x)) # This will be the output: # NameError: name 'math' is not defined
In the above example, we use the Python
math.ceil method without importing the math module.
NameError: name’math’ is not defined was the error message that came up. This happened because the math keyword was not known to the interpreter.
In Python, we must first import the math module before we can use it or any other math method.
Example 3 Solution:
import math x = 5.5 print(math.ceil(x)) # 6
math module was brought in on the first line of code. When you now run the code above, you should get the number 6 back.
