PrintPython contains many data types built in. These include text, numeric, sequence, mapping, sets, Boolean, binary and None. Coding at its core is largely working with data that is in one of these types and it is important to know them and how they work.
As a developer, you need to know types for operations and for parameters and this helps with debugging, performing conditionals, calculations, dictionary operations, and data transformations. For example, the string “1” does not equal the int 1. Trying to add “2” + 5 will result in a TypeError
res = "2" + 5 print (res)
Output
Traceback (most recent call last): TypeError: can only concatenate str (not "int") to str
Changing the 5 to “5” results in concatenation of the “2” and “5”:
res = "2" + "5" print (res)
Output
25
For this course, we will be looking at more advanced structures in the mapping type. W3 provides a great overview of the data types and I encourage you to review them.
