Day 1

What I learnt …. uuuuuggghhhhhh some fantastic staffff!!

Check it out dute:

1. replacement field. So if I want to add something I can use format() method

#this is a replacement field acions

# use of format() method

u = ‘Filip’

pas = ‘trum tum tum’

print ‘{0} is an owner of {1} password’.format(u, pas)

---

and you are getting

>>> Filip is an owner of trum tum tum password

---

Another mojo bojo

# using format() method in list

fixes = [‘KB’, ‘MB’, ‘GB’, ‘TB’, ‘PB’, ‘EB’, ‘ZB’, ‘YB’]

# here I am using {0} – mean first list in fixes

# {0[1]} – mean

first list and second item in that first list

print ‘1000{0[0]} = 1{0[1]}’.format(fixes)

---

>>> 1000KB = 1MB

---

# great method to extract data from string

# split() method I can use only if the data is in some schema

query = ‘user=pilgrim=123&database=master&password=PapayaWhip’

a_list = query.split(‘&’)

print a_list

print

# elem.split() method used for each element in list

# remember if use the number ‘1’ in spliting otherwise if there will be more ‘=’ you will get ERROR!

a_list_of_lists = [v.split(‘=’,1) for v in a_list if ‘=’ in v]

print a_list_of_lists

print

#making dict from list

a_dict = dict(a_list_of_lists)

print a_dict

---

>>>[‘user=pilgrim=123’, ‘database=master’, ‘password=PapayaWhip’]

>>>[[‘user’, ‘pilgrim=123’], [‘database’, ‘master’], [‘password’, ‘PapayaWhip’]]

>>>{‘password’: ‘PapayaWhip’, ‘user’: ‘pilgrim=123’, ‘database’: ‘master’}
