class item:
def __init__(self, name, value=0):
self.name = name
self.value = value
ClassitemRice = item("Rice", 2)
tradeItemSelect = ["Rice"] [#After that, various ingredients...]
for i in range(len(tradeItemSelect)):
itemCount = 'item_{}'.format(tradeItemSelect[i]) # The value you want to get (just a variable)
itemName = 'Classitem{}'.format(tradeItemSelect[i]).name # Value you want to get (class)
What I want to do is classitem{}.I want to get the value of name through the for statement.
I don't know much about Python, so I'm doing it while searching, but if I enter it like this,
'Classitem{}'.format(tradeItemSelect[i]).The name itself is recognized as a string and cannot get the value.
The exec and getattr are similar, but they're a little bit different.
How to use the for statement with the variable value of item_{} and classitem{}.Can I get the value of the name?
python
Importing a string as a variable name means two tasks: (1) interpolating a string and (2) obtaining a class property with that string. Neither (especially in Python) is recommended.
I'm curious about the actual work you want to do. If it is:
Ramen...
# Not tested
totalAmount = 0
ingredients = []
ingredients.push(item('Rice', 2))
ingredients.push(item('Soy Sauce', 0.25))
for i in ingredients :
TotalAmount += i.value # <-- Key
print ("Soy sauce rice totalAmount: " + str(totalAmount))")
I think this is enough.
