We can use this block to trail our code to see if there may be potential for errors to occur. The try block allows us to check and see that our code will throw an error or not. In Python, the NameError exception comes into the picture when we try to use or refer to a name that is not defined locally or globally. There are numerous built-in exceptions available in Python, and One such exception is NameError Exception. The NameError can be avoided by using a technique called Exception Handling.Įven if we write code without any Synta圎rror, the program can result in runtime errors. Synta圎rror can be corrected by following the programming language guidelines in a way the interpreter could understand. When we write our code and if the programming language does not accept it, then arises the Synta圎rror. The most common errors that occur in python is the Synta圎rror & NameError. The NameError can be avoided easily by using the Python Error handling technique or exception handling, which denotes the user about the NameError that is occurring in the block of code without actually throwing an error. Here we fail to put the string inside the quotes, so the console will throw us the NameError. We haven’t imported the numpy library as np, and upon executing the operation, we will see the NameError.Īnother kind of NameError occurs when we fail to insert a string value inside the quotes, and the interpreter identifies it as a variable and throws a NameError. Where if we miss to import the package or library or if we haven’t defined the name of that package or library and upon executing an operation using that library, we will get a NameError There are cases of NameError that also occurs during operations done with a python library or a package. So if we operate on l, which is not defined, it will throw us a NameError.

Only l1 & l2 have been defined, and the interpreter can only identify l1 & l2 variables. Here we are performing a delete operation on a variable l that is not defined. L1 = 100 # muting the 1 st position of l1 to 100 When working with user-defined variables in coding, the NameError often occurs due to the difficulty in identifying the local/global values for the interpreter. It was originally written to perform some operation between two numbers and named as calc_sum, but upon calling it, we used the name calc_su, so it is not defined previously, and it will throw us a NameError.
