This video covers the topic: Create numeric, character vectors(including string) and perform various operations (including logical) on it.
1) Create a numeric vector using 'array' from numpy library and perform various mathematical operations on it. After that, we perform various logical operations.
2) Create a character vector and display it in various ways. Then we create a string and perform basic operations.
3) Demonstrated various ways to create vectors/ sequence.
I have mainly gone through some useful commands:
1. import numpy as np : Import numpy library as np
2. np.array : Create array
3. [ ] : Accessing elements of an array (1 dim)
4. == : Logical 'Equal to'
5. np.logical_and : Logical 'and'
6. np.logical_or : Logical 'or'
7. np.where : Finding index of an array
8. print(''.join()) : Represent a character vector w.o. quote
9. .uppper()/.lower()/.title() : String with all upper/lower/initial capital letters
10. .strip : Represent a string w.o. quote
11. np.concatenate : Join vectors
12. list(range()) : Create vector (Only integer incement)
13. np.arange() : Create vector (Support fractional increment)
