You can use the or operator to assign a “default value” to a variable. This works because a or b is equivalent to a if a else b. Thus you could write lista = GETLISTA() or some_default Notice, however, that this will also use some_default if GETLISTA() evaluates to an empty list [], or any … Read more
It’s not so clear what you’re asking, but here are some options to get you started: Manual Min-max transform You could min-max transform so they are all in the range of [0,1], and then multiply by 255. Then, all your values are in the range of 0 to 255, proportional to your original array (i.e. … Read more
Check the root variable. You might be looking for the file at ./access_log-20150215 that is actually in a subdirectory such as ./subdir/access_log-20150215. If you want to explore all subdirectories use f=open(os.path.join(root,file),’r’) but if you only want the top directory you can use os.listdir(‘.’) 3 solved Python script looking for nonexistent file
That’s what they expect: def sorttuple(a): … do something, like sorting.. return b a=(3,2,1) b=sorttuple(a) print b output: (1,2,3) solved Python Function: Tuple as argument and return sorted [closed]
I don’t see any return statement in the chossen_old_words() function so while you build a dictionary in the function (I suppose it’s the control one), you don’t return it. When you accept the return value in the next_word() function, as I said the chossen_old_words() function returns nothing. However, in Python every function returns something and … Read more

If I got this right, dataset is a matrix, with size 100×30, and you are trying to get a list from it? If this is the case, you can do: dataset = [[x for x in range(30)] for j in range(100)] train_dataset = [dataset[i][j] for i in range(100) for j in range(30)] print(train_dataset) print(len(train_dataset)) dataset … Read more

I read you say that your variable is changing, but where? Two things: you’ve got to change the variable you’re checking AND you have to change that condition test, that while loop condition is True when the variable var[5] is different than ‘left’ or different that ‘right’ (if it’s “left”, then it’s different than ‘right’ … Read more
