Iterate

Iterating over a string
“Simply implement an iterator that defines a next() method, and implement an __iter__ method on a class to make it iterable.”

s = 'abcde'
for c in s:
    print(c)

Reverse

Reverse string in Python (5 different ways)

s = s[::-1]

Software as a service (SaaS)

• Cloud Computing
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
• Desktop as a Service (DaaS)
• Managed software as a Service (MSaaS)
• Mobile backend as a Service (MBaaS)
• Information Technology Management as a Service (ITMaaS)

Centralized hosting of business applications dates back to the 1960s. Starting in that decade, IBM and other mainframe providers conducted a service bureau business, often referred to as time-sharing or utility computing. Such services included offering computing power and database storage to banks and other large organizations from their worldwide data centers.

Snowflake, The Only Data Warehouse Built for the Cloud
Welcome to the Snowflake Documentation
Key Concepts & Architecture

Snowflake is an analytic data warehouse provided as Software-as-a-Service (SaaS). Snowflake provides a data warehouse that is faster, easier to use, and far more flexible than traditional data warehouse offerings.

Snowflake’s data warehouse is not built on an existing database or “big data” software platform such as Hadoop. The Snowflake data warehouse uses a new SQL database engine with a unique architecture designed for the cloud. To the user, Snowflake has many similarities to other enterprise data warehouses, but also has additional functionality and unique capabilities.
