justbard的python实用程序
jblib的Python项目详细描述
jblib
作者：贾斯汀·巴德
编写这个模块是为了尽量减少编写我经常使用的函数的需要。
安装：python3 -m pip install jblib

from jblib import cd
class cd()
Example:
with cd(directory):
print (os.getcwd())
print (os.getcwd()) ## Back at the originating directory on exit
from jblib import hilight
class hilight(string).color(highlight=True, bold=True)
Example:
print (hilight("Hello World").red(bold=True))
Or you could make an object:
text = hilight("Bar")
print ("Foo "+text.blue())
To return the original string:
print (text.string)
Available Colors:
red
green
yellow
blue
purple
teal
white
from jblib import convert_module
Module to convert various data
def convert_time_from_seconds(seconds_given)
Converts a seconds into minutes, hours and days.
def IP2Int(ip)
Converts a IPv4 address to a interger - This is useful to store IP addresses in databases
def Int2IP(ipnum)
Converts a interger back to an IPv4 address
def urlcode(url, encode=False)
Wrapper for urllib.parse.quote and urllib.parse.unquote.
From urllib docs - Replace special characters in string using the %xx escape. Letters, digits, and the characters '_.-' are never quoted. By default, this function is intended for quoting the path section of URL.
- https://docs.python.org/3.1/library/urllib.parse.html?highlight=urllib#urllib.parse.quote
from jblib import HTMLgen
Basic HTML generator
02/09/2019
class HTMLgen(head=False, tail=False, lang="en", docType="html")
FUNCTIONS:
title(self, title, scripts=None, css=None)
body.add(content)
tag(tag, content=False, close=True, cssclass=None)
image(src, alt=None, srcset=None, height=None, width=None, style=None, cssclass=None)
br() <-- Returns a </ br> tag
div(cssclass) <-- Not yet implemented
table() -- Class Object
table.add_row()
table.produce_table()
EXAMPLE:
page = HTMLgen(True, True)
page.title("This is the page Title", scripts="foo.js bar.js", css="styles.css nav.css")
page.body.add(page.image("images/frontpage.jpg", width="100%"))
page.body.add(page.tag("h1", "This is a header line"))
page.body.add("This is another line")
## Creating a table
test_table = HTMLgen.table()
test_table.add_row(["column data 1", "column data 2", "column data 3"])
test_table.add_row(["column data 4", "column data 5", "column data 6"])
## And finally we add the table to the rest of the page
page.body.add(test_table.produce_table())
page.return_html()
```
<!DOCTYPE html>
<html lang="en>
<head>
<title>This is the page Title</title>
<link rel="stylesheet" href="styles.css">
<link rel="stylesheet" href="nav.css">
<script src="foo.js"></script>
<script src="bar.js"></script>
</head>
<body>
<img src="images/frontpage.jpg" width="100%">
<h1>This is a header line</h1>
This is another line
<table>
<tr>
<td>column data 1</td><td>column data 2</td><td>column data 3</td>
</tr>
<tr>
<td>column data 4</td><td>column data 5</td><td>column data 6</td>
</tr>
</table>
</body>
</html>
```
from jblib import progress_bar
Progress Bar
02/25/2019
FUNCTIONS:
progress_bar(progress, barLength=50, text_field="Progress")
EXAMPLE:
counter = 0
for i in range(100):
counter += 1
i = counter/100
progress_bar(i, 50)
sleep(0.1)

from jblib import build_date_array
Build Date Arrays
02/27/2019

EXAMPLE:
dates = build_date_array(days=7, weekend=False)
dates
['2019-02-27', '2019-02-28', '2019-03-01', '2019-03-02', '2019-03-03', '2019-03-05', '2019-03-06']
from jblib import mean_deviation
''' 说明： 此函数将pandas dataframe列带入，然后返回一系列计算出的平均偏差
FUNCTION:
mean_deviation(data, mean=None)
EXAMPLE:
data["MeanDeviation"] = pd.Series(mean_deviation(data['column']), index=data.index)
''
from jblib import standard_deviation
''' 说明： 此函数接受pandas dataframe列，然后返回计算出的标准偏差
FUNCTION:
standard_deviation(data, mean=None)
EXAMPLE:
standard_dev = standard_deviation(data['column'])
''
from jblib import StreamToLogger
DESCRIPTION:
Fake file-like stream object that redirects writes to a logger instance.
CLASS:
StreamToLogger(object)
EXAMPLE:
if log_enabled: ## If true, all standard output and standard error to the console will be disabled
# create logger
logging.basicConfig(format='%(asctime)s - %(message)s', datefmt='%Y%m%d %H:%M:%S', filename=log_file)
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
logger.propagate = False
fh = logging.FileHandler(log_file, "a")
fh.setLevel(logging.DEBUG)
formatter = logging.Formatter(fmt='%(asctime)s - %(message)s', datefmt='%Y%m%d %H:%M:%S')
fh.setFormatter(formatter)
logger.addHandler(fh)
keep_fds = [fh.stream.fileno()]
stdout_logger = logging.getLogger('STDOUT')
sl = StreamToLogger(stdout_logger, logging.INFO)
sys.stdout = sl
stderr_logger = logging.getLogger('STDERR')
sle = StreamToLogger(stderr_logger, logging.ERROR)
sys.stderr = sle
