Typo in functions chapter in Default Argument section

Two typos in function chapter default argument section:

In a function variables may have default argument values, that means if we don’t give any value for that particular variable it will assigned automatically.

there should be be after it will
and in the second paragraph:

In the above example we have written b = -99 in the function parameter list. That means of no value for b is given then b’s value is -99.

typing mistake there is of instead of if

Spelling Error On Generator Chapter

There is a spelling error in the generator chapter of the book.

One way to create a reusable generator is Object-based generators which does not hold any state. Any class with an iter method which yields data can be used as an object generator. In the following example, we will recreate our counter generator.

Put this edited paragraph instead, the old paragraph was this:
One way to create a reusable generator is Object based generators which does not hold any state. Any class with a iter method which yields data can be used as a object generator. In the following example we will recreate out counter generator.

With article mistakes and punctuations and spelling errors.

PEP 8 part is misleading

Your PEP 8 part at http://pymbook.readthedocs.io/en/latest/pep8.html is rather bad. It differs from the actual current PEP 8 and you make it look misleadingly official. Better use the actual current PEP 8 text, add a clear header saying that this is only a copy, and link to the original. Though I really don't get the point of copying it in the first place. I think it would be best for you to only summarize PEP 8, briefly explaining what it is, giving a few important examples, and then referring to the original document on the Python site for people interested in the whole thing.

I btw came across your page as the fifth result in a google search for "pep8" (and I see your GitHub repository is quite popular). So it's not insignificant. It might actually be misleading people already.

Add pep8 details in a new chapter

Data Structures chapter typo in a.remove

In Data Structures chapter, List section and in demo of remove function a.remove that block has visible rst ::

Operators section needs some modification for division

In Operators ,

>>> 22.0 / 12
1.8333333333333333

To get floating result you need to the division using any of operand as floating number.

The above line is not valid for Python 3 as we don't require the operand as floating number to get a floating result. So this line should be modified.

>>> 22 / 12
1.8333333333333333

In the same article we should also add some example about floor division for python.

Typo in Data Structures chapter in remove() method

As the screenshot above the description of remove() method starts as "If you want to any...", it will be "If you want to remove any..."

Update the syntax for python3

http://pymbook.readthedocs.org/en/latest/looping.html

In the power series section it is given x = float(raw_input("Enter the value of x: "))
it should be x = float(input("Enter the value of x: ")) for python3

License and Copyright of this repo

This is a great resource I have found. But through out the book, or the repo,

1. I couldn't find a license under which the book is released under.
2. I am also not sure, if the right credits is given to the other contributors. I don't find them mentioned anywhere, except when I come in to GitHub and click on Contributors.

PS : If I were to choose a license of the book, I would choose CC- Public Domain. So that people who are further using/re-using the book are not constrained in any manner of permissions.

Minor Error in example

In https://pymbook.readthedocs.io/en/latest/thebeginning.html change
... a = 12 + 34

print(c) #this is a comment too :)
into
print(a) #this is a comment too :)

Add a chapter on Microsoft Technology Associate Exam

items() methods in dict instead of iteritems() for python3

pym/docs/datastructure.rst

iteritems() method is deprecated in python3
Replace all instances with items() instead.

wrong formula

I think matrix multiplication example in https://github.com/kushaldas/pym/blob/master/docs/datastructure.rst is wrong, should be like this:
c = []
for i in range(0, n):
c.append([])
for j in range(0, n):
c[i].append(sum([a[i][k] * b[k][j] for k in range(0, n)]))

Missing License

Thanks for the wonderful work that you and the community has done. I think it would be a nice idea to have an explicit license so the terms of usage, editing and redistribution are clear.

Typo in functions chapter

Here in 1st example of local and global variables the code is:
print "After the function calls ", a]
It will be like
print "After the function calls ", a

Add chapter on the SQL operation

It will be great to add a chapter of handling SQL Operation in the book. We can discuss about the topic like how to execute SQL CRUD Operations and use of ORM library like SQLAlchemy.

Section on Shorthand Operators not strictly true

I am referring to http://pymbook.readthedocs.io/en/latest/operatorsexpressions.html#shorthand-operator. x op= y is not always equivalent to x = x op y. The statement is always true for immutable objects like ints and tuples. Mutable objects, on the other hand, can have a completely different implementation of the shorthand operators since those operators can modify the object in-place. For example, lists define a legitimately different __iadd__ operator (which is basically extend).

Add a chapter on basic logging details

need indendation in a line

In this piece of code,

https://github.com/kushaldas/pym/blob/master/docs/operatorsexpressions.rst#evaluateequpy

print "%2d %6.4f" % (i , sum)

should be indented. it should come inside the for loop.

fix this.

Thanks.

Broken link on homepage?

The sentence at the top of the homepage that points the user to the Python 2.x version of the book appears to be incorrect. It points to this 3.x homepage rather than a homepage for the 2.x version of the book.

Your book has been plagiarised

Start Python 3 ! by Seyed Hossein Ahmadpanah is a ripoff of your book and is sold on Amazon (https://www.amazon.com/Start-Python-Seyed-Hossein-Ahmadpanah/dp/1511625554/ref=asap_bc?ie=UTF8). The guy has been confirmed as plagiarising 8 books at least and we have managed to get some taken down by complaining to Amazon. Good luck and keep me informed, please (jan @ newmarch.name)

raw_input() is not anymore supported in Python3.x

You need to change the raw_input() to input() as in Python3.x raw_input() is not anymore supported.

Give visible links for Downloading PDF, epub versions

It is difficult to find the download link on the book's home page.

The bottom right link with green color letters (v:latest) does not mean for downloading.

Give the links for PD. epub on the left panel itself.

Thanks.

Typo error in the Installation chapter

In Installation chapter, under On GNU/Linux point, there is a usage of word bellow:

Install the latest Python from the distribution’s repository.

For Fedora 23 and above Python3 is in the system by default.

For Fedora 22 and bellow.

The correct word is below.

for x in range(1,10)

pym/docs/igd.rst

for x in range(1,10) is 1-9, not 1-99

Typo in functions chapter

In functions chapter in first paragraph last line there is usage of word build in:

Reusing the same code is required many times within a same program. Functions help us to do so. We write the things we have to do repeatedly in a function then call it where ever required. We already saw build in functions like len(), divmod().

the correct word is not build in, rather its built-in
