====== Python Cheat Sheet ======

===== Comments =====

# - Pound sign

<code python>
# This is a comment
ob = bpy.data.objects["Panel"]
</code>

===== Data types =====

List

<code python>
a = [1,4,5,6,9,10]
print (a[0])
    1
print (a[1:2])
    4, 5
</code>

<code python>
a = 'hellothere'
print (a[4:])
   'othere'
</code>

Dictionary (like a hash map)

<code python>
a = {}

a['name'] = 'bob'
a['age'] = 44
print (a)
   {'age': 44, 'name': 'bob'}
</code>


===== Functions =====

<code python>
def myfunction(aNumber=1, aString="hello"):
    result = ''
    for i in range(aNumber):
       result += aString
    return result
</code>

===== Syntax =====

Indents matter, usually 4 spaces.

===== Loops =====

<code python>
for i in range(2,10):
    print (i)
</code>

or use ''xrange(2,20)'' for lazy, as-needed streaming of content.

===== Conditional =====

<code python>
if a ==10:
   print 'yes'
else:
   print 'no'
</code>

===== Class =====

<code python>
class Boy()
    def setName(self, n):
       self.name = n
    def getName(self):
       return self.name
</code>

self is like *this* in Java. If you don't provide "self," you are referring to the global variable.

<code python>
b = Boy()
b.setName("bob")
</code>

===== Display =====

(Don't forget the parentheses.)

<code python>
print ("Hello, world!")
</code>
