How to Find the String Length
I presume you might have contemplated the question: "Why should I bother calculating the character count within a string? I seek simplification..." However, Python boasts an extensive repertoire of built-in functions, and among these, determining the length of a string using len()
is a fundamental and frequently employed operation in programming. Allow me to illustrate this with an example, which should elucidate the concept further:
Note
Please take note of the
len()
function; it calculates the number of items within the string, which can be referred to as the string's length.
Task
Time to practice:
- Get the last index of the variable
string
using negative indexation and assign it to the variablesymbol1
. - Extract the index of the last symbol of the variable
string
using thelen()
method and assign it to the variablesymbol2
.
Note that len(word)
equals the length of the word, but len(word)-1
equals the index of the last symbol of the word.
Everything was clear?
