A solution could be to also set the end variable in the first if-statement, depending on your needs. Let us look at all the approaches to solve the NameError. The Python "NameError: name 'sqrt' is not defined" occurs when we use the sqrt function without importing it first. "NameError: name 'reduce' is not defined" happens when you use the reduce () function, it has been removed from the built-in functions in Python 3 and moved to the 'functools' module. python - NameError: name '_mysql' is not defined after setting change to mysql I have a running Django blog with sqlite3 db at my local machine.

JSON.LOADS and EVAL can turn S to the object in Python, JSON.LOADS converts the string in JSON into Unicode (Types.unicODetyPE), EVAL is turned into Str (Types.StringType). Method 1 - Importing NumPy with Alias as np The simplest way to resolve this error is by providing an alias as np while importing the NumPy library. What is it that you are trying to do? Here pd is an alias of the pandas module so we can either import pandas module with alias or import pandas without the alias and use the name directly. Note that sometimes you will want to use the class type name inside its own definition, for example when using Python Typing module, e.g. Python cannot find the name "calculate_nt_term" in the program because of the misspelling. Misspelling the name of a variable, a function or a class (names are case-sensitive). What I want is to. main.py # NameError: name 'math' is not defined print(math.ceil(1.2)) print(math.floor(1.7)) Method 1: By using the alias when importing the pandas. Here is an example of how the error occurs. Also, if possible, I would suggest avoiding using global variables like this, as explained in this Stack Overflow post. Resources for IT Professionals. if myVar is None: print('The value None exists') Output: The value None exists Summary Here are the methods to help you solve the NameError: name " is not defined error in Python.

The Python "NameError: name 'operator' is not defined" occurs when we use the operator module without importing it first. There is information on how to set up and use pipelines in the documentation ( https://www.quantopian.com/docs/user-guide/tools/pipeline ). You are using Python 3, and You are following a tutorial designed for Python 2. At some point we are not able to switch anymore beetween render layer and the "reduce" error happen.

To solve the error, import the operator module before using it - import operator. NameError: nome "reduce" no est definido em Python 8689184 NAMEERROR NAME REDUCE IS NOT DEFINED IN PYTHON. The same python code is executing successfully on my local machine without any warning and errors. nameerror: name 'mean' is not defined. This can be harder to find if you have written a very long program. But I am getting the error " NameError: name 'reduce' is not defined " consistently on my python code. Here is an example of how the error occurs. Let's fix our code by providing an alias and see what happens. Those aren't "other errors", they're an attempt to explain what is currently happening in your code. In the Python programming language, NameError: name 'request' is not defined occurs when working with Flask or . Now to make use of reduce (), we need to import functools: import functools anon = lambda x,y: x+y sum = functools.reduce(anon, [1,2,3,4]) print(sum) The output of the code: 10 We can make it easier within our code to use the from keyword to import reduce: Traceback (most recent call last): File "***", line 67, in <module> main(sys.argv) NameError: name 'main' is not defined. main.py name 'reduce' is not defined It happen when using Render Layers on some of our scenes. The classically Pythonic way, available in Python 2 and Python 3.0-3.4, is to do this as a two-step process: z = x.copy() z.update(y) # which returns None since it mutates z In both approaches, y will come second and its values will replace x "s values, thus b will point to 3 in our final result. (Either outside any function, or in a function where it's declared global). Python raw_input function reads the input and returns a string. The Margin class you have imported is a subclass of KucoinBaseRestApi. main.py # NameError: name 'operator' is not defined print(operator.add(10, 20)) b) Defining a variable out of the scope. Azure Machine Learning service from tkinter import * from tkinter import messagebox def test_show(): messagebox.showinfo(None, 'first') query. Example: value = ['Mango', 'Apple', 'Orange'] print (value) After writing the above code, Ones you will print " value " then the output will appear as a " [ 'Mango', 'Apple', 'Orange'] ".
