Using tqdm progress bar in a while loop

I am making a code that simulates a pawn going around a monopoly board a million times. I would like to have a tqdm progress bar that is updated every time a turn around the board is achieved. Below is my current code. I am using a while loop which stops when the number of turns around the board surpasses the desired number. import os from openpyxl import Workbook from monopolyfct import * def main(runs, fileOutput): ### EXCEL SETUP ### theWorkbook = Workbook() # Creates the workbook interface. defaultSheet = theWorkbook.active # Creates the used worksheet. currentData = ["Current Table Turn", "Current Tile"] # Makes EXCEL column titles. defaultSheet.append(currentData) # Appends column titles. ### CONTENT SETUP ### currentData = [1, 0] # Sets starting position. defaultSheet.append(currentData) # Appends starting position. while currentData[0] <= runs: ### ROLLING THE DICES PROCESS ### dices = twinDiceRoll() currentData[1] += dices[2] # Updating the current tile ### SURPASSING THE NUMBER OF TILES ONBOARD ### if currentData[1] > 37: # If more than a table turn is achieved, currentData[0] += 1 # One more turn is registered currentData[1] -= 38 # Update the tile to one coresponding to a board tile. else: pass ### APPENDING AQUIRED DATA ### defaultSheet.append(currentData) ### MANAGIING SPECIAL TILES ### if currentData[1] == 2 or 15 or 31: # Community chess pass #TODO: Make a mechanic simulating the community chest card draw and it's related action. elif currentData[1] == 5 or 20 or 34: # Chance pass #TODO: Make a mechanic simulating the chance card draw and it's related action. elif currentData[1] == 28: # Go to Jail pass #TODO: Make a mechanic simulating the entire jail process ### TWIN DICE ROLL EXCEPTION ### if dices[3] is True: # If the dices roll a double, pass #TODO: Make a mechanic considering that three doubles sends one to Jail. ### STORING THE ACCUMULATED DATA ### theWorkbook.save(fileOutput) # Compiles the data in a .xlxs file. if __name__ == "__main__": terminalWidth = os.get_terminal_size().columns # Gets current terminal width. space(3) print("Python Monopoly Statistics Renderer".upper().center(terminalWidth)) # Prints the title. print("(PMSR)".center(terminalWidth)) # Prints the acronym. space(2) runs = int(request("For how many table turns do you want the simulation to run?")) # Prompts for the desired run ammount #runs = 1000 fileOutput = request("What should be the name of the file in which statistics are stored?") # Prompts for the desired store filename #fileOutput = "test" fileOutput += ".xlsx" # Adds file extension to filename main(runs, fileOutput)
You can use manual control in tqdm by specifying a total argument in the constructor. Verbatim from the manual: with tqdm(total=100) as pbar: for i in range(10): sleep(0.1) pbar.update(10) UPDATE To manually control the tqdm without the context manager (aka with statement), you will need to close the progress bar after you are done using it. Here is another example from the manual: pbar = tqdm(total=100) for i in range(10): sleep(0.1) pbar.update(10) pbar.close() For this to work you need to know the total number of expected runs. In your code it could look something like ... pbar = tqdm(total = runs+1) while currentData[0] <= runs: ### ROLLING THE DICES PROCESS ### dices = twinDiceRoll() currentData[1] += dices[2] # Updating the current tile ### SURPASSING THE NUMBER OF TILES ONBOARD ### if currentData[1] > 37: # If more than a table turn is achieved, currentData[0] += 1 # One more turn is registered currentData[1] -= 38 # Update the tile to one coresponding to a board tile. pbar.update(1) else: pass ... pbar.close() However, this code isn't perfect: consider if the currentData[1] is always less than 37 -- the progress bar will just stop and not update. If you try to update it in the else:... part, you might violate the total upper bound. This is a start tho :)
