python question for matrix

It means that the code does not make sense Python. We would like to define a vector with four numbers. DO THIS: Fix the following code to creat three vectors with four numbers. [ ]: x = Z = ([1, 2, 3.4, 4]) ([1, 2, 3, 5]) ([1, 2, 3, 6.3]) Although you may have been able to get rid of the error messages the answer to you problem may still not be correct. Throughout the semester we will be using a python program called answercheck to allow you to check some of your answers. This program doesn't tell you the right answer but it is intended to be used as a way to get immediate feedback and accelerate learning. DO THIS: First we will need to download answercheck.py to your current working directory. You only really need to do this once. However, if you delete this file by mistake sometime during the semester, you can come back to this notebook and download it again by running the following cell: [38]: from urllib.request import urlretrieve urlretrieve('https://raw.githubusercontent.com/colbrydi/jupytercheck/master/answercheck.py', 'answercheck.py'); DO THIS: How just run the following command to see if you got x, y and z correct when you fixed the code above. [45]: from answercheck import checkanswer checkanswer(([x,y,z]), 'e80321644979a873b273aebbbcd0e450'); NameError Traceback (most recent call last) in 1 from answercheck import checkanswer 2 ----> 3 checkanswer(((x,y,z]), 'e80321644979a873b273aebbbcde450'); NameError: name 'y' is not defined
