After several weeks of doing 3 passes on 40+ tutorials sticking to the path, the way the author teaches them, hoping that unresolved questions will be answered later in these tutorial(s), this pass I’m trying to answer questions raised by the tutorials themselves

Running test code, trying to figure out the answers to some of these questions, like with dictionaries, having a string key name, with an integer value, curmfd.update({"[1,2]": 76}) seems to work to add a string key, with an integer value, but I'm having trouble building a variable for curmfd.update to do the same thing.

I'm using it as a lookup structure to store associated integer values to be used later, these will be built in a loop.

Can anyone point me to a working example?

curmfd = {} # start blank dictionary p = 2 # project number pn = 2 # programmer number lnk = 200 # ppn block link # ppn = f"[{p},{pn}]: {lnk}" # input PPN number ppn = [1,4] # ppn = '{[' + str(p) + ',' + str(pn) + ']: ' + lnk + '}' curmfd.update({"[1,2]": 76}) # add key '[1,2]', value 76 curmfd.update({"[1,4]": 78}) # add key '[1,4]', value 78 curmfd.update({"[1,6]": 164}) # add key '[1,6]', value 164 # curmfd.update(ppn) # add key '[2,2]', value 200 # x = curmfd["[2,2]"] # get value for key '1,4' curmfd.update({"[7,0]": 220}) # add key '[7,0]', value 220 # print(str(x)) # print value for key '2,2' for t in curmfd.keys(): print(t + " ", end='') # print keys print(curmfd[t]) # print values
