Using python
In my code:
print('Menu')
menu_items = ['pizza','burger','hotdog','salad']
menu_price = ['10','7','4','8']
print('0)',menu_items[0], '$', menu_price[0])
print('1)',menu_items[1], '$', menu_price[1])
print('2)',menu_items[2], '$', menu_price[2])
print('3)',menu_items[3], '$', menu_price[3])
I get: Menu
pizza $ 10
burger $ 7
hotdog $ 4
salad $ 8
I dont want a white space between the $ and the value, how would I do this
CodePudding user response：
You could use an f-string.
print(f"0) {menu_items[0]} ${menu_price[0]}")
And with a format specifier to ensure the price is printed correctly.
print(f"0) {menu_items[0]} ${menu_price[0]:.2f}")
Alternatively, you can specify the separator to print as being an empty string, and then manually add spaces where necessary.
print('0) ', menu_items[0], ' $', menu_price[0], sep='')
One more thing
Structuring your data as multiple arrays works, but it's a bad design. You'd be better off keeping your related data stored together.
Rather than:
menu_items = ['pizza', 'burger', 'hotdog', 'salad']
menu_price = ['10', '7', '4', '8']
Store this as a list of tuples storing the description and price of each item.
menu_items = [('pizza', 10), ('burger', 7), ('hotdog', 4), ('salad', 8)]
Now if you want to print these with numbers, you can use enumerate and a for-loop.
for index, (description, price) in enumerate(menu_items):
print(f"{index:-2d}) {description:20s} ${price:4.2f}")
And the result is:
0) pizza $10.00
1) burger $7.00
2) hotdog $4.00
3) salad $8.00

Try this :)
print('0)', menu_items[0], '$' str(menu_price[0]))
(Technically, the string conversion is not necessary in this case - since your menu_price array already contains strings)

You can use this:
print('Menu')
menu_items = ['pizza', 'burger', 'hotdog', 'salad']
menu_price = ['10', '7', '4', '8']
[print(f"{i}) {menu[0]} ${menu[1]}") for i, menu in enumerate(zip(menu_items, menu_price))]
