30. Write a Python program to create the following dataframe using a dictionary of lists: [3]
Product Price Quantity
0 Chair 1500 100
1 Table 3000 50
2 Lamp 500 200
3 Sofa 5000 20
Or
Write a Python program to create a Pandas series, as shown below, using a dictionary. Note that the left
column indicates the indices and the right column displays the data.
Dog 13 years
Cat 15 years
Elephant 60 years
Ans. import pandas as pd
f_data = {
"Product": ["Chair", "Table", "Lamp", "Sofa"],
"Price": [1500, 3000, 500, 5000],
"Quantity": [100, 50, 200, 20]
}
df = pd.DataFrame(f_data)
print(df)
Or
import pandas as pd
data = {"Dog": "13 years", "Cat": "15 years", "Elephant": "60 years"}
series_animalifespan = pd.Series(data)
print(series_animalifespan)
31. (a) Write an SQL statement to create a table named VEHICLES with the following specifications:

Column Name Data Type Key
VehicleID Numeric Primary Key
Make Varchar(50)
Model Varchar(35)
Year Numeric
Price Numeric
(b) Write an SQL query to insert the following data in VEHICLES table:
