Python is similar to other languages like Java, .NET, PHP, Ruby, and Golang. It is highly readable, has many easy to install libraries, and allows the developer to focus on logic rather than syntax. Python code is simple, with "Hello, World" only requiring one line of code. Key reasons for adopting Python include its large community of users from different fields and its readability. The document also provides examples of procedural and object-oriented Python programs.

1. Python 100.1
An overview of python for existing developers
by Gerald Quisumbing

2. How is it similar
to ...
Java
.NET
PHP
Ruby
Golang

3. Key reasons for adoption
The language is used by people from all
walks of life from dark hat hackers to
scientists to data analysts.
➔ Highly readable
Code is often self explanatory especially
if you follow idiomatic python
➔ Plugins easy to add
Lots of libraries to use and easy to
install
➔ Focus on logic
You can focus on your ideas instead of
worrying about syntax

4. Simplest modern way to do “Hello, World.”
>> print “Hello, World!”
Hello, World!
#Python 2.7 version
>> print(“Hello, World!”)
Hello, World!
#Python 3.x version
Tip
A python program
will generally use
the python
interpreter but can
be run as a script
or daemon

5. Zen of Python
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
...
Tip
Import this

6. Dynamic type language
X=100
X=”Hello, World!”
Tip
Developers from
strictly typed
languages will
often find this odd.

7. Sample simple program
import random
#import line comment
“””Multiline comment
Comment”””
def myfunc():
pass
Tip
Sometimes bad
habits arise from
the ability to get
away with just
about anything

8. Sample procedural program
import random
def myfunc:
number = random.randint(1,20)
return number
print myfunc()
Tip
A lot of pythonista
code this way. A lot of
non-developers
prefer to code this
way. This can quickly
lead to hard to
maintain code.

9. Object oriented program
import random
class MathDude:
def myfunc(self):
number = random.randint(1,20)
return number
mdude=MathDude()
print mdude.myfunc()
Tip
I would
recommend this
way for larger
projects: easier to
unit test, easier to
maintain
