pjen - Simple static website generator

I've created a simple static website generator called pjen. The GitHub repository can be found here.

```
import os

class pjen:
def __init__(self, path=None):
"""
By default, the path will be set to the current working directory,
or the path can be specified using the 'path' keyword parameter.
"""

if path is None:
self.path = os.getcwd()
else:
self.path = path

self.path += "/website"

def create_project(self):
"""
Creates an initial file structure for a project at the specified path.

An exception is raised if a project already exists in the desired location.

Creates the following file structure:

website
|-> templates
|-> group1
|-> images
|-> scss
|-> css
|-> scripts

"""

if not os.path.exists(self.path):

#make the root directory
os.makedirs(self.path)

os.makedirs(self.path+"/templates")
os.makedirs(self.path+"/templates/group1")
os.makedirs(self.path+"/images")
os.makedirs(self.path+"/scss")
os.makedirs(self.path+"/css")
os.makedirs(self.path+"/scripts")

print("Created project in {}".format(self.path))

else:
raise IOError("A directory already exists at: {}".format(self.path))

def _count_indent(self, str, tab_equiv=4):
"""
Returns the number of leading spaces. A tab is counted as 'tab_equiv' spaces.
"""

i = 0
count = 0

while(str[i] == " " or str[i] == "\t"):

if str[i] == " ":
count += 1
if str[i] == "\t":
count += 4

i += 1

return count

def _sanatise_file_list(self, l, fname=None):
"""

is is broken:

>>> 1000 is 10**3
False
>>> 1000 == 10**3
True

You can read more about this here, but in short it's better to use ==.

Ternary statements:

I really like ternaries, so I may be a little biased, but you can use ternary statements to simplify logic:

if path is None:
        self.path = os.getcwd() 
    else:
        self.path = path

into:

self.path = path if path != None else os.getcwd()

while loop:

Instead of using a while loop, you can simply iterate using a for loop:

(also, Python does not require explicit brackets around the loop)

(also, str[i] cannot be both " " and "\t", so you can use a elif for the second one.)

while(str[i] == " " or str[i] == "\t"):

        if str[i] == " ":
            count += 1
        if str[i] == "\t":
            count += 4

        i += 1

    return count

into:

for item in str:
        if item == " ":
            count += 1
        elif item == "\t":
            count += 4

    return count
