Core parts

Currently, there are 3 core parts in my program.

1. Send email in Gmail with Python

Send email in gmail account with Python.
Here will be one popular quetion for "Login credentials with Gmail SMTP".

2. Check availiabilty in website (Amazon)

Checking availaility in amazon website with product's ID.

# checking availaility 
XPATH_AVAILABILITY = '//div[@id ="availability"]//text()'
RAw_AVAILABILITY = doc.xpath(XPATH_AVAILABILITY) 
AVAILABILITY = ''.join(RAw_AVAILABILITY).strip()

This will return the result of product's availabilty based on its ID.

3. Check Top 5 products from Amazon's Best Seller page

Checking Top 5 best seller products from recommanded page.

# check for product link in href
XPATH_HREF = '//span[@class = "aok-inline-block zg-item"]/a[@class ="a-link-normal"]/@href'
RAw_HREF = doc.xpath(XPATH_HREF) 
#print(type(RAw_HREF)) # list

This will return a list for links for those 5 best-seller products.
