2) CSV to JSON<\/h2>\n
import csv,json\nprint (json.dumps(list(csv.reader(open('csv_file.csv')))))<\/span><\/pre>\n
3) Apply regular expression to lines from stdin<\/h2>\n
import sys,re\n[sys.stdout.write(re.sub('PATTERN', 'SUBSTITUTION', line)) for line in sys.stdin]<\/span><\/pre>\n
4) Profile a Python script<\/h2>\n
python3 -m cProfile foo.py<\/span><\/pre>\n
5) Start a Webserver on your current directory<\/h2>\n
python -m SimpleHTTPServer 8000<\/span><\/pre>\n
6) Finding all subsets of a set in one line<\/h2>\n

9) Largest 8-Bytes Number<\/h2>\n
print '\\n'.join(\"%i Byte = %i Bit = largest number: %i\" % (j, j*8, 256**j-1) for j in (1 << i for i in range(8)))<\/span><\/pre>\n
10) Retrieve content text from HTTP data<\/h2>\n
