In the following text string, we can identify each character using an index.
word = "Python""P" index 0 ... or ... - 6
"y" index 1 ... or ... - 5
"t" index 2 ... or ... - 4
"h" index 3 ... or ... - 3
"o" index 4 ... or ... - 2
"n" index 5 ... or ... - 1
If we want to refer to any index we will do it in the following way between brackets [ ]:
print (word[3])'h'
print (word[-5])
> 'y'We can do SLICING (Slicing), that is, take slices from that previous text string:
print (word[2:-1]) # A slice from index 2 to -1 but without taking the latter'tho'
print (word[:2]) # From the start (since we have left it empty)
# to position 2, but without taking the latter, that is, index 0 and 1'Py'
If we do not specify between the brackets, no number will be collected from the beginning to the end [:]
On the contrary, if we indicate an index that does not exist, we will get an error.
