[PYTHON] I made a program to input what I ate and display calories and sugar
Background
Recently, it seems that the sugar-restricted diet is popular, so when I thought I had tried it, I arrived at the Ministry of Education, Culture, Sports, Science and Technology website and started to think that it was just right for the task.
Various data
Download the Standard Tables of Food Composition in Japan Excel (Japanese version) (collective) from Ministry of Education, Culture, Sports, Science and Technology
There is data that is entered as a character string, so please be careful when using it for calculations etc. (sic)
Please note that. Put it in the same directory.
Download the illustration from Illustration and. Rename it to ** fat.png ** and put it in the same directory.
Creating anguish
――It was painful to say from the conclusion I made ――I was reminded of the troublesomeness of GUI --98% of the time it took was suffering from GUI ――CUI is enough for you to make your own ――Tkinter doesn't seem to be very good in the first place (I don't know) ――The determination to make a GUI again has sprung up. ――At first, I wanted to be able to change the size of the window, but I gave up.
GUI part
--The specifications of pack () are still unclear. --I used place () as a compromise. (Time taken: about half a day) --The search field is a little elaborate. (Time taken: about 5 minutes) --Other pack () arguments are messed up. ――I don't know which one you need or don't need, but it's good because it's working! !! !! !!
main.py
self.frame5 = tk.Frame(self.root, width=self.root.winfo_width() * 0.6, height=self.root.winfo_height() * 0.1, bg="#CCFFCC")
self.button2 = tk.Button(
self.frame5, text="calculate", font=(u'Meiryo', 17), width=40)
self.button2.bind("<Button-1>", self.show_result)
self.frame5.place(x=512, y=648)
self.frame5.pack_propagate(0)
self.button2.pack(expand=True)
self.root.mainloop()
Processing part
--A bug occurred when float was initially set to int ――Judged that all floats are OK ――I think there is a more beautiful method --Judged as impossible due to the balance with GUI (not impossible at all) ――It's good because it's moving! !! !! !!
main.py
self.list2 = self.listbox2.get(0, tk.END)
self.list3 = self.listbox3.get(0, tk.END)
self.list3 = [float(i.replace("(g)", ""))*0.01 for i in self.list3]
self.cal = 0
self.toshitsu = 0
for i in range(len(self.list2)):
self.number = self.shokuhinmei.index(self.list2[i])
self.cal += self.eiyolist[self.number][5]*self.list3[i]

self.toshitsu += float(self.eiyolist[self.number]
[16])*self.list3[i]
self.frame1.destroy()
self.frame2.destroy()
self.frame3.destroy()
self.frame4.destroy()
self.frame5.destroy()
self.canvas = tk.Canvas(self.root, width=1280, height=720)
self.pngfile = tk.PhotoImage(file="fat.png ")
self.cal = str(round(self.cal, 1)) + "kcal"
self.toshitsu = str(round(self.toshitsu, 1)) + "g"
self.canvas.create_image(400, 400, image=self.pngfile)
self.canvas.create_text(900, 180, text="Calorie intake",
font=(u'Meiryo', 60))
self.canvas.create_text(900, 300, text=self.cal,
font=(u'Meiryo', 60, "bold"), fill="red")
self.canvas.create_text(900, 420, text="Amount of sugar ingested",
font=(u'Meiryo', 60))
self.canvas.create_text(900, 540, text=self.toshitsu,
font=(u'Meiryo', 60, "bold"), fill="red")
self.canvas.place(x=0, y=0)
Finished product
--There was no particular problem other than suffering from GUI ――I received advice that it is better to use a method for reuse, so I changed it a little.

Execution result
Conclusion
I'm glad that what I was thinking was in shape. However, I think there are many improvements, so I would like to fix them.
