The while Loop

while <expr>:
<statement(s)>
<break> #will take you out of the loop
<statements>
<continue>
<statements>

<statements> #break will bring you here


Example:
x = 10
while x > 0:
x -= 1
if x == 5:
break
if x == 8:
continue #Don't print when its 8
print(x)

print("outside loop")

Pandas SQL Example - Reproducing SQL Queries In Python

In this video on reproducing SQL queries in Python using Pandas library, I am going to show you Pandas SQL examples on how to write pandas code reproducing sql statements.

Using pandas, i will show you how to get sql results in python like
* grouping and aggregation on multiple columns in pandas, similar to sql groupby clause
* sorting by multiple columns, reproducing sql order by clause
* filter multiple conditions, which involves where conditions with multiple columns

and a lot more...
