DONT HARDCODE SPLIT() FUNCTION

Assuming full name is seperated by space
e.g 'john smith', 'issac newton' and you want to split to
firstname and lastname

fullname = 'john smith'
#avoid this
name= fullname.split(' ')
firstname = name[0]
lastname = name[1]
print(firstname, lastname)

#pythonic way 
firstname, lastname = fullname.split(' ')
print(firstname,lastname)

UNDERSTAND isinstance() METHOD USING A SIMPLE QUESTION

if someone ask you
"is mr.A from Nigeria?"

the reply is either yes or No i.e True or False

that is the same question you are asking whenever isinstance() method is invoked

"Is object A from class Z?"

e.g isinstance(1,int)
is the same as asking, "is 1 from int?" in which the answer is True

For this code:

text = input('Enter a string: ')
for i in range(len(text)):
	if text[i] == a:
		print(i, end=',')

If i type in 'amalgamate', I'll get the following output: 0,2,5,7,

Question: How can I discard that comma after 7?

This my solution might not be best algorithm but it solve it

text = 'amalgamate'
stop=text.rfind('a')
for i in range(len(text)):
    if text[i] == 'a':
	      if i != stop:
	         print(i,end=',')
	      else:print(i,end='.')

You're good, man.

i wrote a sparseMatrix ADT implementation. But i am trying to figure out better way to complete the __mul__ implementation. Would you be kind enough to check if there is a better way. Its a long code and works perfectly though but the time-complexity of the __mul__ implementation seems very long.

Here i have the link to the complete code on Github: https://github.com/Predstan/Algorithm-and-Data-Structure/blob/master/ch4/sparseMatrix.py

Python is gaining popularity on the web as well as mobile app development due to its robust, powerful, interactive programming language that is easy to learn and reduces development time. Highly interactive, cross-platform support, object-oriented, open-source are some of the highlighting features of Python that lure developers to adapt it.

Python has a wide range of frameworks to offer to make things easier for developers. They are mainly categorized into,

Full Stack Python Framework

1. Django
2. TurboGears
3. Web2py


Non-Full Stack Python Frameworks

1. CherryPy
2. Flask
3. Bottle

Can you give worked example of matrix multiplication output you want, because only dot product i can remember now....dont mind me oo

Its a sparse Matrix with several Zero elements. So i used a List for the elements(non zero) in the Matrix and another class to store the row number, col number and value. So the zero elements does not accupy any space in the ADT.
To Multiply two matrices, we first calculate transpose of the second matrix to simplify our comparisons and maintain the sorted order. So, the resultant matrix is obtained by traversing through the entire length of both matrices and summing the appropriate multiplied values.
Any row value equal to x in the first matrix and row value equal to y in the second matrix (transposed one) will contribute towards result[x][y]. This is obtained by multiplying all such elements having col value in both matrices and adding only those with the row as x in first matrix and row as y in the second transposed matrix to get the result[x][y].

Storing rows using nested list would have been easy...right now,i haven't think what best algorithm will be better.
