In [65]: df
Out[65]:
one two
one 1 4
two 2 3
three 3 2
four 4 1
In [66]: df.drop(df.index[[1,3]])
Out[66]:
one two
one 1 4
three 3 2
Here is what the above code is Doing:
1. df.index returns the index of the dataframe
2. df.index[[1,3]] returns the index of the rows you want to drop
3. df.drop(df.index[[1,3]]) drops the rows with the index 1 and 3
def text_splitter(t): t = re.sub(r'[^\w\s]’,”,text) data = pd.DataFrame(columns=[‘text’,’output’]) for i in range(len(t.split())): text = ‘ ‘.join(t.split()[0:i+1]) temp_text = ‘ ‘.join(t.split()[i+1:]) for k in range(len(temp_text.split())): output = ‘ ‘.join(temp_text.split()[:k+1]) # print(text,’—-‘,output) data = data.append({‘text’:text, ‘output’:output}, ignore_index=True) return data t = ‘How do I reset a password in windows’ text_splitter(t) text output 0 How do 1 How…
try: a=2 except: pass Here is what the above code is Doing: 1. It’s creating a variable called a and assigning it the value 2. 2. It’s using a try/except block to catch any errors that might occur. 3. If an error does occur, the code in the except block will be executed. 4. In…
\n is the classic line_feed on Unix/Linux (his ascii is 10 in decimal and 0a in hexadecimal) \r\n is the classic line_feed on Windows \r is the classic line_feed on olds version of MacOs (pre-MacOsX version) (his ascii is 13 in decimal an 0d in hexadecimal) Here is what the above code is Doing: 1….
new_list = [x+1 for x in my_list] Here is what the above code is Doing: 1. We create a new list called new_list. 2. We iterate through each element in my_list. 3. For each element in my_list, we add 1 to it and append it to new_list. 4. We return new_list.
t1 = pd.to_datetime(‘1/1/2015 01:00’) t2 = pd.to_datetime(‘1/1/2015 03:30’) print pd.Timedelta(t2 – t1).seconds / 3600.0 Here is what the above code is Doing: 1. Convert the strings to datetime objects 2. Subtract the two datetime objects to get a timedelta object 3. Convert the timedelta object to seconds 4. Divide by 3600 to get hours
from bs4 import BeautifulSoup import html5lib myFile=open(‘C:/Users/CSE/AppData/Local/atom/app-1.42.0/practise.html’,’r’) soup=BeautifulSoup(myFile,”html5lib”) print(soup.prettify()) Here is what the above code is Doing: 1. We open the file in read mode. 2. We create a BeautifulSoup object by passing two arguments: a. The HTML content b. The HTML parser we want to use. In our case, we’ll be using html5lib. 3….
