I have a .txt file that looks like this:
Title | Author ------------------------- title1 | author1 title2 | author2 ... ... titleN | authorN
I want to extract 100 random titles from this file, like this:
title1 title2 ... title100
I tried this:
import random with open('file.txt','r') as f: title = f.read().split('|') for i in range (0,100): print(random.choice(title))
But during the execution, the program prints also random authors name. How can I avoid this?
When you do this:
with open(path,'r') as f: title = f.read().split('|')
f.read() gives you the whole files as a string. Splitting that on
| gives a list with both authors and titles (and new lines and spaces).
Instead, you can process the lines and split as you go. With something like:
with open(path) as f: titles = [l.split('|').strip() for l in f]
This will give you a clean list of titles like:
['title1', 'title2', 'title3', 'title4', 'title5']
With that you can use
random.sample() to get however many random items you want.
import random path = "path/to/file.txt" n = 100 with open(path) as f: titles = [l.split('|').strip() for l in f] random.sample(titles, n)
This assumes you don't want duplicates.
Python File I/O: Read a random line from a file, import random def goal_word(min_length=7, filename="words.txt"): You don't need to read the whole file in at once nor use random.choice() if you use the The algorithm is based on the idea that you select later samples� with open ('lorem.txt', 'rt') as myfile: # Open lorem.txt for reading text contents = myfile.read () # Read the entire file to a string print (contents) # Print the string. Note. Indentation is important in Python. Python programs use white space at the beginning of a line to define scope, such as a block of code.
You can use
.readlines() instead of
.read() to read the file line by line to a list. Then you can use
.split('|').strip() after when you've selected a random row, to only show the title part of it:
import random with open('file.txt', 'r') as f: title = f.readlines() for i in range(0, 100): choice = random.choice(title) print(choice.split('|').strip())
Alternatively you can process the file immediately after you've read it:
import random with open('file.txt', 'r') as f: title = [line.split('|').strip() for line in f.readlines()] for i in range(0, 100): print(random.choice(title))
Here's a demonstration how the
>>> choice = "title1 | author1" >>> choice.split('|') ['title1 ', ' author1'] >>> choice.split('|') 'title1 ' >>> choice.split('|').strip() 'title1'
Pick a random big word from a list of words using Python, random number file reader - python python read file line by line. I have a text file that has six words on one line, I need to randomly generate a word from that line � In this article, I am going to let you know how to extract text from a PDF file in Python. Before diving into the topic, a lot of things need to be configured. The pdftotext module is used as the main component to extract text.
Have a look at
title after you read it in. If my text file is
title1 | author1 title2 | author2
title will be
['title1 ', ' author1\ntitle2 ', ' author2\n']. Randomly choosing from this list will sometimes give you titles, sometimes authors, and sometimes both.
A better approach would something like the following:
import random # read in the file and split lines with open("file.txt", "r") as f: lines = f.read().splitlines() # lines = ["title1 | author1", "title2 | author2"] titles = [line.split("|").strip() for line in lines] # titles = ["title1", "title2"]
Note that we need to call
strip to strip any extra whitespace off the ends of the title.
You can now proceed with your sampling, but I suspect that you want 100 unique titles and not just 100 random titles. What you are doing is called sampling with replacement, and getting unique titles would be sampling without replacement. You can accomplish this with
random.sample as follows (see the random docs):
print(*(random.sample(titles, 100)), sep = "\n")
or equivalently with more familiar syntax
for samp_title in random.sample(titles, 100): print(samp_title)
Pulling a random word/string from a line in a text file in python, Secondly, do not use file as one of your variable names. As you can see above, file is highlighted in purple meaning that it is a reserved word in Python.

The following are constraints to get a random line: The file path must be specified to open the file on the computer. We must specify the mode of the file while the file is opening. Importing Random Module:
