There are few best practices to follow when naming a variable in Python. Name a is not defined. To fix it you must figure out why the variable is not definedthe most frequent bugs are 1 to use the variable or function name in the code before it was defined or 2 to misspell the name in either the definition or the usage.

File line1 in File line6 in main File line5 in function1 Name Error. Here variable a is global. Use only small case letters numbers and underscores for python variable name.

I have no idea why it thinks average finish is a global. You define the global variable at the module level. Search SearchSearchpatternb NameError.

We will see what happens if we create a variable of same name as global variable inside the function. If you look at the above code snippets the variable names are random. If Python encounters a name that it doesnt recognize youll probably get this error.

2000 Traceback most recent call last. File tmpdefine_namespacepy line 9 in printa NameError. Python3 tmpdefine_namespacepy Traceback most recent call last.

So the user_answer_easy_test_1 you defined in play_easy_text is not available in check_correct_easy_text. X 1 def display. As it is declared outside the function and can be used inside the function as well.

Identifiers defined outside any function or class have global scope these may include functions variables and classes. NameError is raised when the identifier being accessed is not defined in the local or global scope.

Global name --- is not defined Python knows the purposes of certain names such as names of built-in functions like print. Global VVV in a function actually does not define VVV as a global variable. Also the keyboard I use on my laptop isnt working so I typed in the code on my tablet.

Globals returns a dictionary of elements in current module and we can use it to access modify the global variable without using global keyword ie. The global variable with the same name will remain as it was global and with the original value. They dont convey the meaning of the variables.

If you create a variable with the same name inside a function this variable will be local and can only be used inside the function. Global name b is not defined But I have already defined this global variable. As global keywords hide the local variable with same name so to access both the local global variable inside a function there is an another way ie.

How does not called a global variable name as easy to python supports multiple variables can achieve it always used in it will be done often written hundreds of parameters.
