Hi,
I am trying to create a portfolio of shares, each share is entered manually
while checking it against a list of actual share codes.Its working mostly as
intended at the moment, except when I print the table out at the end, I want
all entered details printed as such
Enter command: addEnter share code to add: tpwTPW = TrustPowerEnter share
price: 2Enter share quantity: 5Enter command:
print----------------------------------Code Price Quant
Value----------------------------------TPW 2.00 5
10.00----------------------------------Total cost:
10.00==================================
**(This is all even when displayed in Wing101)
So thats all fine, but I'm wanting muiltiple more rows printed underneath with
other shares and their prices etc. Getting stuck on that, I know i'll need a
for loop to iterate over the input but still wanting to get some help.
here's the rest of the code so far.
PROMPT_FOR_COMMAND = 'Enter command: 'PROMPT_FOR_CODE = 'Enter share code to
add: 'PROMPT_FOR_PRICE = 'Enter share price: 'PROMPT_FOR_QUANTITY = 'Enter
share quantity: '
MESSAGE_UNKNOWN_COMMAND ='Unknown command - please try
again.'MESSAGE_UNKNOWN_CODE = 'Unknown code - CANCELLING code
entry.'MESSAGE_PORTFOLIO_EMPTY = 'No shares in portfolio.'MESSAGE_GOODBYE =
'Thankyou and goodbye.'
TITLE_TEMPLATE = '{:<6}{:>8}{:>8}{:>12}'LINE_ITEM_TEMPLATE =
'{:<6}{:>8.2f}{:>8}{:>12.2f}'LINE_TOTAL_TEMPLATE = '{:<20}{:>14.2f}'SPACER_LINE
= 34 * '-'DBL_SPACE_LINE = 34 * "="
def print_portfolio_table(portfolio): """ Prints out a portfolio table as
per specification. You can use the test_print_portfolio_table to test this
function...""" print(SPACER_LINE) print(TITLE_TEMPLATE.format("Code",
"Price", "Quant", "Value")) print(SPACER_LINE)
print(LINE_ITEM_TEMPLATE.format(code, price, quant, (price * quant)))
print(SPACER_LINE) print(LINE_TOTAL_TEMPLATE.format("Total cost:", (price *
quant))) print(DBL_SPACE_LINE)
def process_add_code(portfolio): """Receives a portfolio list. Asks for a
share code. If it's in the exchange then prints code = fullname then gets
price and quantity from the user then it appends the (code, price, quantity)
to the portfolio""" global code code = input(PROMPT_FOR_CODE).upper()
if shares.in_exchange(code) == True: print(code + " " + "=" + " " +
shares.get_name(code)) global price price =
float(input(PROMPT_FOR_PRICE)) global quant quant =
int(input(PROMPT_FOR_QUANTITY)) portfolio = portfolio.append([code,
price, quant]) main() else: print(MESSAGE_UNKNOWN_CODE)
main()
def main(): """This is the main function for the program, ie, this function
is called first when the program is run""" # The portfolio list will
contain tuples as (code, price, quantity) # Initially it is empty
portfolio = [] command = input(PROMPT_FOR_COMMAND).lower() if command ==
'add': return portfolio.append(process_add_code(portfolio)) if
command == "print" and len(portfolio) <= 1:
print_portfolio_table(portfolio) return main() if command == "quit":
print(MESSAGE_GOODBYE)
