Hello guys,
i am new to programming and trying to solve this small coding: my purpose is to
take in values from the user based on a menu provided for selection
the output looks like this...
please select from the following menu:
1. pizza
2. steak
3. pasta
4. burger
type in any number from above for selection..
you have selected: 1. Pizza
The bill amounted for Pizza is $20 along with tax of $0.15 will make upto $20.15
the code i have written for this is as follows:
print """
Please select from the following menu:
1. pizza
2. steak
3. pasta
4. burger
type in any number from above for selection..
"""
pz = raw_input()
pz = int(pz)
st = raw_input()
st = int(st)
ps = raw_input()
ps = int(ps)
bg = raw_input()
bg = int(bg)
There should only be one input statement:
choice = int(raw_input())
The program now requires 4 inputs, which is not what you want.
Since you are starting, consider using 3.3 insteadd of Python 2 unless
you have a very good reason.
if pz == 1 :
if choice == 1:
etc.
print "You have selected", pz, ".pizza"
pr_pz = 20
tx_pz = 0.15
tot = pr_pz + tx_pz
print "The bill amounted for Pizza is $", pr_pz, "along with tax of $", tx_pz,
"willmake upto $", tot
Take out 'amounted'
elif st == 2 :
print "You have selected", st, ".Steak"
pr_st = 40
tx_st = 0.20
print "The bill amounted for Steak is $", pr_st, "along with tax of $", tx_st,
"will make upto $", tot.....................
...........................
but my program doesn't output the selection once i type in any number from the
list.
Because it is waiting for 3 more inputs. See above. Now, you can shorten
and improve the program after the one input statement.
data = (
('Pizza', 20.0, 0.15),
('Steak', 40.0, 0.20),
('Pasta', 14.0, 0.12),
('Burger', 23.0, 0.17),
)
if 1 <= choice <= len(data):
product, price, tax = data[choice]
bill = "The bill for {} is {}, along with tax of {}, total {}"
print(bill.format(product, price, tax, price + tax))
else:
print('I do not know what you mean.')
print() is for 3.x, but works here for 2.x also.
