1.Python Built-in Packages - Hands-on 1

Welcome to Python Built-In Packages-1

1.1)Python Built-In Package-SYS

import sys

import os

import io

def func1(a):

    s=sys.stdout.write(a)

    return s

if __name__ == "__main__":

1.2)Python Built-In Package-OS

import os

#Write your code here

s = os.getcwd()

os.mkdir('New Folder')

os.chdir(r'./New Folder')

q = os.getcwd()

os.chdir(s)

os.rename('New Folder','New Folder2')

os.chdir(r'./New Folder2')

p = os.getcwd()

os.chdir(s)

os.rmdir('New Folder2')

w = os.getcwd()

with open('.hidden.txt','w') as outfile:

     outfile.write(s)

with open('.hidden1.txt', 'w') as outfile:

     outfile.write(q)

with open('.hidden2.txt', 'w') as outfile:

     outfile.write(p)

with open('.hidden3.txt', 'w') as outfile:

     outfile.write(w)

1.3)Python Built-In Package-DATETIME

import os

import datetime

def func1(y,m,d,ms,se,da,mi):

    input_date = datetime.date(y,m,d)

    input_date1= datetime.datetime(y,m,d,ms,se,da,mi)

    t= input_date1 - datetime.timedelta(days=3,minutes=2,seconds=2,microseconds=1)

    day = t.day

    year= t.year

    month = t.month

    minute= t.minute

    second= t.second 

    return input_date,input_date1,t,day,year,month,minute,second

def func2(y,m,d,ms,se,da,mi):

    input_date2 = datetime.datetime(2020,1,3,10,34,24)

    f = "%a %b %d %H %M: %S %Y"

    s= input_date2.strftime(f)

    x= datetime.datetime(y,m,d,ms,se,da,mi)

    q= x.strftime(f)

    z= datetime.datetime.strptime(q,f)

    return x,q,z

if __name__ == "__main__":

1.4)Python Built-In Package-SHUTIL

import os 

import shutil 

# Source path 

source = (r'/projects/challenge/New Dir/newww.txt')

  

# Destination path 

destination = (r'/projects/challenge')

  

# Copy the content of 

# source to destination 

dest = shutil.copy(source,destination)

  

  

# Print path of newly  

# created file 

print("Destination path:", dest) 

with open('.hidden.txt','w') as outfile:

  outfile.write(dest)
