Design-of-experiment (DOE) matrix generator for engineering and statisticsĬopyright (c): 2018-2028, Dr. Print('outside function myVars:', myVars) MyVars.renameVariable('myconst', 'myconstOther') MyVars = 14 # <- this raises an error, since 'myconst' must not be changed You'd use the class like this: from variableVariablesManager import VariableVariablesManager That said, I've implemented a variable variables manager-class which provides some of the above ideas.

to raise an exception on overwriting for different types.

you can decide to overwrite existing variables or.

however, you are much more flexible, e.g.

if you want to rename a variable name, you'll have to do it manually.

there's either no locality or globality for variable variables, it depends on the globality of the dictionary.

you'll yourself be responsible for this dictionary, including garbage collection (of in-dict variables) etc.

This is a good idea for most cases, however, there are many aspects arising from this: The consensus is to use a dictionary for this - see the other answers. Num0, num1, num2, num3, num4, num5, num6, num7, num8, num9 = listA Using globals(), locals(), or vars() will produce the same results #īonus (creating variables from strings) # Python 2.7.16 (default, Jul 13 2019, 16:01:51)Ĭreating variables and unpacking tuple: g = globals()

Use a list for a sequence of similar objects, a set for an arbitrarily-ordered bag of objects, or a dict for a bag of names with associated values. If query = keyword_1 or query = keyword_2: Instead of something like this: keyword_1 = 'apple' If you simply need a 'bag' of objects, this can be a great choice. The 'base' variable name becomes the name of the list and the varying identifier is used to access it.įinally, don't forget other data structures, such as the set - this is similar to a dictionary, except that each 'name' doesn't have a value attached to it. The result in either case is a populated list, with the first element accessed with my_calculator.buttons, the next with my_calculator.buttons, and so on. This list can also be created in one line with a comprehension: my_calculator.buttons = This can be assembled as follows: my_calculator.buttons = This is particularly true if your data are homogeneous, such as daily temperature readings, weekly quiz scores, or a grid of graphical widgets. However, if you're simply trying to create many variables and you don't mind referring to them with a sequence of integers, you're probably looking for a list. If the program requires arbitrary variable 'names,' a dictionary is the best choice, as explained in other answers. My_calculator.('button_%d' % i) = tkinter.Button(root, text=i)

VARIABLE DATA CREATOR HOW TO

However, they get stuck on how to dynamically create those variable names, and may try something like this: for i in range(10): The more astute beginner observes that the only difference in each of those lines is a number that changes based on a rule, and decides to use a loop. The coder is then left with a pile of named variables, with a coding effort of O( m * n), where m is the number of named variables and n is the number of times that group of variables needs to be accessed (including creation). My_calculator.button_2 = tkinter.Button(root, text=2) My_calculator.button_1 = tkinter.Button(root, text=1)

New coders sometimes write code like this: my_calculator.button_0 = tkinter.Button(root, text=0)
