update.message.photo is an array of photos sizes (PhotoSize objects).


update.message.photo



Use file = bot.getFile(update.message.photo[-1].file_id). This will get the image with biggest size available.


file = bot.getFile(update.message.photo[-1].file_id)





why i should write "[-1]" ? what is this?

@Ali [-1] is the last item of array. This is how indices work in python. I recommend getting familiar with it as it's very common feature. You actually don't have to use the last item, but last image is the biggest image according to docs (github.com/python-telegram-bot/python-telegram-bot/wiki/…)

How to input without newline? (Python)

How to input without newline? (Python) I am trying to create a simple file editor in Python via the console (called PyCons). Here is my current program: def PyCons(f): file = open(f, "r") appe = open(f, "a") print("n=====nPyCons Editor, v1.2nPython 3.6.1n") global i i = 0 for line in file: i += 1 print(" {}| ".format(i) + line, end='') for k in range(10000000000000): print("n {}| ".format(i+1), end='') inp = input("") if inp == "@PyCons.save()": print("n=====") break else: i += 1 appe.write("n" + inp) I used the end method to make sure that the existing code in the file was printed properly in its line format, but the input function does not have an end attribute. So, when I go to enter code in the editor: end input end PyCons("magic.html") ... ===== PyCons Editor, v1.2 Python 3.6.1 1| <p>Hello!...
