Can u use for loop here (python dictionary problem)[SOLVED]

Question

x=input()
car = {
'brand':'BMW',
'year': 2018,
'color': 'red',
'mileage': 15000
}
if (x=='year'):
print(car['year'])
elif x=='color':
print(car['color'])
elif x=='mileage':
print(car['mileage'])
elif x=='brand':
print(car['brand'])

Answer 1

you could use loop for this task, but the more pythonic way would be to use dict.get(key) method ;)

Answer 2

You in no way need a loop, but here.

Answer 3

key = input()
car = {
'brand':'BMW',
'year': 2018,
'color': 'red',
'mileage': 15000
}
for k, v in car.items():
if k==key:
print(v)

... or few shorter (but onelined):

print(next(v for k, v in car.items if k==key))

Answer 4

Goku ,
Yes, you can surely use for loops.

Everyone has already shown above 👆 how it can be solved in different ways using for loops.

Answer 5

Goku

Yes you can use loop even you can directly get the value by just passing key as car is a dictionary.

See this

-------1st way------

for i in car:
if i == x:
print (car[i])

-------2nd way--------

print (car[x])

You can also iterate dictionary like this

for key in car:
print (key)

So here input can be compare with key but not with key: value pair as you said

Answer 7

Goku,
As others have mentioned, use of loop is possible, but its necessity should be considered thoroughly. For example, if you want to print the key-value pairs from dictionary <car> you can do

for ( key, value ) in car.items():
print( f"{key} : {value}" )

But if you only want to output one of the pairs (if any match), you can use subscript operator [], or use `get()` method https://www.w3schools.com/JUMP_LINK__&&__python__&&__JUMP_LINK/ref_dictionary_get.asp

Answer 8

Your program needs to take the key as input and output the corresponding value.

Sample Input:
year

Sample Output:
2018

Shivani 📚✍ [Exams]
I got the output using if ..but can we add loop in this task

Answer 10

Goku,
Why you think we need a loop there? I don't get why we need a loop though;

Answer 11

Ipang
I just want to know that we can use loop or not

Answer 12

🅘🅜 🅰🅹 !!! the input is a string and that code would comapre a string to a dict key:value pair. You could do car.keys() tho

Answer 13

Slick

Well keys are also string so no problem here

Answer 14

car = {...}
x = input()

# ~~~ Method 1:

print(x.get(x, "\0"))

# ~~~ Method 2:

if x in car: print(car[x])

# ~~~ Method 3 (slow):

[print(car[y]) for y in car if x == y]

# Hope this helps

Answer 15

Alot of ways we can use it, but the way you do is important.

Answer 16

car = {'brand':'BMW', 'year': 2018, 'color': 'red', 'mileage': 15}

key = input()
print(car[key])

Answer 17

I prefer to use switch instead if elif
