Python Forum

I've been searching the internet for the answer to my problem, but to no avail. I'm trying to put data into rows and columns, but I have variables and I thought that I had found the answer to my problem, but it wasn't a solution to the variable part of it. Is there a way that I could modify this method a little bit to include variables or is there another way to do this?

#inputs name = input("Who are you? ") supermarket = input("Where are you going? ") date = input("What day is it? ") item = input("What are you buying? ") price = float(input("How much is the item you are buying? ")) quantity = float(input("How many are you buying? ")) vehicle = input("How do you plan to get there? ") commute_cost = float(input("How much does that cost one way? ")) #process total = price * quantity total_commute_cost = commute_cost * 2 trip_total = total + total_commute_cost #data for column data = '''\ Item Price Quantity Total item price quantity total''' #making the table into columns and rows rows = [ line.strip().split(' ') for line in data.split('\n') ] cols = zip(*rows) col_widths = [ max(len(value) for value in col) for col in cols ] format = ' '.join(['%%%ds' % width for width in col_widths ]) #output print(" ") print("Shopper name:", name) print(" ") print(supermarket) print(date) print(" ") for row in rows: print (format % tuple(row))

with an output of

Output:
Item Price Quantity Total item price quantity total

but I want an output, if the variables have been answered by the user,

Output:
Item Price Quantity Total Milk 4 2 8

im having a real hard time trying to find anything about it.
thanks ahead of time.

you could use pandas:

code:

from CreateDict import CreateDict import pandas as pd class MyApp: def __init__(self): self.cd = CreateDict() self.data = {} def dispatch(self): self.get_data() def add_row(self): name = input("Who are you? ") if name.strip() == 'quit': return 'quit' dnode = self.cd.add_node(self.data, name) supermarket = input("Where are you going? ") self.cd.add_cell(dnode, 'destination', supermarket) date = input("What day is it? ") self.cd.add_cell(dnode, 'date', date) item = input("What are you buying? ") self.cd.add_cell(dnode, 'item', item) price = float(input("How much is the item you are buying? ")) self.cd.add_cell(dnode, 'price', price) quantity = float(input("How many are you buying? ")) self.cd.add_cell(dnode, 'Quantity', quantity) vehicle = input("How do you plan to get there? ") self.cd.add_cell(dnode, 'vehicle', vehicle) commute_cost = float(input("How much does that cost one way? ")) self.cd.add_cell(dnode, 'commute_codt', commute_cost) return 'ready' def get_data(self): retval = None print("add data for each user, type 'quit' when done") while retval != 'quit': retval = self.add_row() self.cd.display_dict(self.data) print() df = pd.DataFrame.from_dict(self.data) print(df) def main(): ma = MyApp() ma.dispatch() if __name__ == '__main__': main()

You will need this module (same directory as main script) please use script name shown

you will need to add error checking, and add code to prevent crashes.

Add first data i structure eg list, dictionary.
Then can use f-string or eg python-tabulate.
Don't use old string formatting anymore %ds % .
Example.

from tabulate import tabulate item = 'Milk' price = 100 quantity = 5 total = 500 item_lst = [] item_lst.append(item) item_lst.append(price) item_lst.append(quantity) item_lst.append(total) lst = [] header = ['Item', 'Price', 'Quantity', 'Total'] lst.append(header) lst.append(item_lst) # f-string for inner in lst: print(''.join((f"{word:<10}" for word in inner))) print('-' * 35) # python-tabulate print(tabulate(lst)) print(tabulate(lst, tablefmt="fancy_grid")) print(tabulate(lst, tablefmt="github"))

Output:
Item Price Quantity Total Milk 100 5 500 ----------------------------------- ---- ----- -------- ----- Item Price Quantity Total Milk 100 5 500 ---- ----- -------- ----- ╒══════╤═══════╤══════════╤═══════╕ │ Item │ Price │ Quantity │ Total │ ├──────┼───────┼──────────┼───────┤ │ Milk │ 100 │ 5 │ 500 │ ╘══════╧═══════╧══════════╧═══════╛ |------|-------|----------|-------| | Item | Price | Quantity | Total | | Milk | 100 | 5 | 500 |

Also eg Pandas easier to manipulate data eg NoteBook.
