Convert Types
At times, Python may automatically assign a data type to a variable, which might not align with our intended choice. Hence, it is advantageous to possess the capability to exert control over the data type selection.
For instance, we can turn a number into a string, change the type of numerical data, or even use whichever number as a boolean data type. In this chapter, we are going to take care of converting numerical data types.
First and foremost, take a look at the syntax of converting a number to the integer data type:
1234567value1 = int(657.89) value2 = int(90e3) value3 = int("678") print(value1) print(value2) print(value3)
Note
It has a simple syntax,
int(number)
, but if we want to convert a string to an integer, this string should contain integer numbers in quotes, likeint("8990")
, notint("899.0")
.
Swipe to start coding
You're working on an application that receives readings from three different sensors: temperature, altitude, and pressure. All sensors return float values, but your database only accepts integers.
- Use the
int()
function to convert each reading into an integer.- Convert
temperature_celsius
intointeger1
. - Convert altitude_meters into integer2.
- Convert
pressure_pascal
intointeger3
.
- Convert
- Each resulting variable must be of type
int
. - Store the final results in the variables
integer1
,integer2
, andinteger3
.
