Parameters
www.edureka.co/python
• A web-crawler is also known as a web spider,
automatic indexer or simply crawler.
• It is an internet bot that helps in web indexing
• Web crawlers helps in collecting information
from a webpage and the links related to them
• It also helps in validating HTML code and
hyperlinks.
• They crawl one page at a time until all the
pages are indexed.
Start: Starting point of the sequence
Step: Number of times the skip will
happen
Stop: Ending point of the sequence

8. Range With For Loop

To install scrapy, simply run the following command in
the command prompt or in the terminal, or simply you
can add the package from the project interpreter too.
for i in range(0,10):
print(i, end=“,”)
#this will print the numbers from 0-9

Range

def frange(start, stop, step):
i = start
while i < stop:
yield i
i+= step
for i in frange(0.5, 1.0, 0.1):
print(i , end=“,”)

for i in range(5,0,-1):
print(i , end=“,”
#the output will be 5,4,3,2,1

14. Range vs
XRange
www.edureka.co/python
The major difference between range and
xrange is that range returns a python list
object and xrange returns a xrange object.
If you require to iterate over a sequence
multiple times, it’s better to use range
instead of xrange.
For the most part, range and xrange
basically do the same functionality of
providing a sequence of numbers in order
however a user pleases.
In python 3, xrange does not exist anymore,
so it is ideal to use range instead. Any way
we can use the 2to3 tool that python
provides to convert your code.

18. Points To
Remember
www.edureka.co/python
The range function in python only works with integers or whole
numbers.
Arguments passed in the range function cannot be any other data
type other than an integer data type.
All three arguments passed can be either positive or negative
integers.
Step argument value cannot be zero otherwise it will throw a
ValueError exception.
The range function in python is also one of the data types.
You can access the elements in a range function using index values,
just like a list data type.
