Question

How to access value for key “Price” in the following Python Dictionary: [1]

mystock = {"Product": "Earphone","Price": 800,"Quantity": 50,"InStock" :"Yes"}

A. mystock[“Product”]

B. mystock(“Product”)

C. mystock[Product]

D. mystock(Product)​

Answer 1

Answer:

mystock["Product"]

Explanation:

You need to tell the program you're talking about a string here which is "Product" and not an identifier called "Product".

You can check this for yourself,

#assigning an identifier with a value

a=5

#define a dictionary and set one of the keys equal to the identifier's value,

d={1:"nopsies", 2:"grow up", 5:"apples", "5":"ohno"}

#Use the key to get the value from dictionary and print it

print(d[a])

print(d[5])

print(d["5"])

You will notice that print(d[a]) and print(d[5]) will return the same values i,e "apples" but "5" will return "ohno" since a is an identifier with value 5
