I have to make pdf markers and update their first page with those markers. I saw many previous publications related to this, but none answered my question correctly. I want to know how I can identify pdf sentences that are bold and larger. I can identify that from the docx file but I can not do it by pdf. Can anyone give me an advantage that I can start? Or it is possible to convert pdf to doc. Update that doc file and convert that doc file back to pdf in Python.

python – Get the link of an image with Xpath
I explain what I'm doing and what I want to do, I'm getting the information from a page but it loads the images by javasccript, to get them I post to the server to return the piece of html that contains them. For some reason that escapes my understanding, I can not pick up the link correctly using Xpath, this "html" that the server returns to me:
These are all Xpaths that are used but none with the desired result:
print response.xpath ('// a / @ href') #no take the entire link
print "-------------------------------------------"
print response.xpath ('// img') #no take the entire link
print "-------------------------------------------"
print response.xpath ('// img[@class=vc_gitem-zone-img]') #empty
print "-------------------------------------------"
print response.xpath ('// *[@class=vc_gitem-zone-img]') #empty
print "-------------------------------------------"
print response.xpath ('// @ href') #no take the entire link
print "-------------------------------------------"
print response.xpath ('// @ src') #no take the entire link
print "-------------------------------------------"
print response.xpath ('normalize-space (// a / @ href)') # do not take the entire link
print "-------------------------------------------"
print response.xpath ('// *[@class=vc_gitem-zone-img]/ @ src ') #vacio
The last one that is used is this:
response.xpath ('// a / @ href')
And in console it returns the link half as the others:
data = u'http: //www.siie.com/wp-content/uploads/2 '>
Thanks for your time.
python – How can I create a function for my code?
-3
I'm completely new to python and I'm learning it. I have written the following code but I could not do any function of it. Can anybody help me please?
import pandas like pd
import numpy as np
f = open (& # 39; 1.csv & # 39 ;, & # 39; r & # 39;)
df = pd.read_csv (f, usecols =[0], sep = " t", index_col = False)
Primary_List = df.values.tolist ()
x = 0
y = len (Primary_list)
for i in the range (x, y):
x = i
MyMatrix = Primary_List[x:x + 10]
print (MyMatrix)
python – Primes and SemiPrimes in binary
I am in the middle of re-learning python. My current effort is an implementation around the prime factorization. I'm trying to reproduce something similar to the table found here (in binary):
https://math.stackexchange.com/questions/586010/relative-size-of-most-factors-of-semiprimes-close
The performance seems to be quite terrible. I have examined the profile of the code in cProfile but I do not see any obvious improvement.
I'm considering:
(a) Install PyPy to see if that improves performance and
(b) Take more advantage of Numpy, although it is precisely a bit vague for me. I am working on the following to see if you can help:
https://www.freecodecamp.org/news/if-you-have-slow-loops-in-python-you-can-fix-it-until-you-cant-3a39e03b6f35/
I've already refurbished to eliminate the need for a semiprime list and that helped a bit, but I'm not sure if there are obvious inefficiencies that I'm not seeing.
miller_rabin.py is not mine. I include it here to complete. My effort focuses on the performance of prime_stats_bin.py. I acknowledge that the primality test will be an important component of the cost, I just do not understand why I can not get to 32 bits in a reasonable time. I am running this on a laptop with Windows 10 for 5 years (Core i5, 2.5GHz, 8GB RAM), under Python 3.7.3 (installed yesterday).
Any comment will be welcome.
As for the purpose of this effort, I would like to know if it is reasonable to expect an output for prime numbers of up to 32 bits from this program in a day.
With 32 bits in the main expansion, the list of prime numbers that I generate is approximately 2xe ^ 8, which, given my installation of 32-bit Python, I'm not sure it's maintained.

Python to sharepoint without credentials
I'm working on a project that wants me to connect to corporate SharePoint and download files using scripts. But they do not want to put a username and password in the scripts or give credentials. How can I access sharepoint from the company's computer? I guess I can assume that everything is connected, so I do not need to enter passwords.
How do I calculate the average rating of a .txt file in Python?
I'm struggling with a Python mission. From a txt.file file, the average rating of each mentor must be calculated. The data in the txt.file file looks like this:
name middle name ________ 6.7 3.5 7.7
name second name ________ 5.1 2.3 8.4
name middle name ________ 7.0 6.0 9.4
This is the code I made:
import systems
def print_grades (input_grades):
degree = input_grades.split ()
grade 1 = degree[0]
grade2 = degree[1]
grade 3 = degree[2]
average_grade = (grade 1 + grade2 + grade3) / 3
def print_mentor (mentor):
mentor_name = mentor.split ("_")
name = mentor_name[0]
ratings = mentor_name [1]
print_grades (input_grades)
& # 39; & # 39; & # 39; Start Program & # 39; & # 39; & # 39;
mentor_grades = open (& # 39; class_grades.txt & # 39;). readlines ()
for mentor in mentor_grades
print_mentor (mentor)
Obviously, this will not result in an output like:
The middle note of the second name is 5.6
The middle note of the second name is 6.3
Can someone help me with the coding to get the output in the previous format?

Handling dates and comparisons Python, Pandas and Excel
I have a date and time column[TRANSFER_DATE] in an excel sheet shows the dates formed as
1/4/2019 0:45 when this date is selected, it appears as
04/01/2019 00:45:08 am using a Python script to read this column[TRANSFER_DATE] which shows the date and time as 01/04/2019 00:45:08
However when I try to compare the column[TRANSFER_DATE] with another date I get this error
Only .dt accessor with datetimelike can be used "
ValueError :: "Only the .dt accessor can be used with values similar to those of the data" when evaluating
which implies that those values are not really recognized as date and time values
mask_part_date = data.loc[data[‘TRANSFER_DATE’].dt.date.astype (str) == & # 39; 2019-04-12 & # 39;]
