Useful Converting
The int()
function can be useful if you're working with numerical data. For instance, imagine that we have a lot of numbers that need to be modified, but all of them have a string data type. This code leads to an error:
value = "123" new_value = value + 10 print(new_value)
Here, Python tries to concatenate the strings, but indeed its functionality doesn't allow it to do so, since 10 is related to the integer data type (concatenation can be applied only to strings).
To correctly sum these numbers, you should initially transform the string into an integer using int()
function:
value = "123" new_value = int(value) + 10 print(new_value)
Swipe to start coding
You're working on a small e-commerce platform. Users submit product prices through a form — but all the values are passed as strings.
Before saving the data or performing calculations, you need to convert the prices into integers, adjust them, and store the updated values in new variables.
- Convert the string value of
price_laptop
to an integer, add 15, and store the result innew_price_laptop
. - Convert the string value of
price_headphones
to an integer, add 780, and store the result innew_price_headphones
. - Convert the string value of
price_monitor
to an integer, subtract 90, and store the result innew_price_monitor
.
All final results must be stored as int values.
