Points to ponder
They are sequence of Unicode characters and can be used with single or double quotes to represent string and multi-line type of strings can be denoted by “OR”.
s = "This is a string"
print(s) # will print the string no need to define
List [ ] can be used with string and it is immutable can be changed.
Slicing String
It means we can concatenate from any character from the string starting with 0 index. For example in hello, h is started with index 0, e is index 1, l is index 2, l is index 3 and o is index 4.
Write the below code and see the output :
s = 'Hello world!'
print(s[4]) # o is index 4 will print o
print(s[6:11]) # will print 'world' as index 6 is started with w and 11 is d
Dictionaries
They are unordered collection pairs of key-value and used to huge amount of data.
In python dictionaries are defined with {} with each item being is part of key value.
