How to generate random sentences containing specific keyword in any language with python

How to generate random sentences containing specific keyword in any language with python

For certain applications it might be useful to generate random sentences containing specific word. One of such cases can be generation of some examples for language learning website.

Generating such sentences manually is time consuming task, hence for this purpose we can leverage generative AI.

Will be using OpenAI API. We can communicate with the API in plain English.

Register for your openai API key at For more info about the API see

First, create python virtual environment and install the openai package using pip:

~/Desktop/openai_API$ python3 -m venv .env
~/Desktop/openai_API$ source .env/bin/activate
~/Desktop/openai_API$ pip install openai

Create a file with the openai private API key and add following contents into it:

Next, import the openai module and set your API key in the main script:

import openai

openai.api_key = config.OPENAI_API_KEY

Now you can call the OpenAI GPT API using the openai.Completion.create() method.

Our main Python script that is calling the OpenAI API

import sys
import os
import openai

import config  # file in the same directory as our

openai.api_key = config.OPENAI_API_KEY

model = "text-davinci-003"
max_tokens = 850

keyword = sys.argv[1]
print('CLI param: ', keyword)

language = 'Japanese'
#keyword = '空港'

prompt = f"Create 5 example sentences in {language} language containing keyword {keyword}. \
For each sentence show transcription to romaji and translation to English. \
Example sentences should be medium length, sometimes even longer. \
Output format should be: \
japanese keyword | \
Kanji: japanese sentence | \
Romaji: romaji transcription | \
Translation: english translation | \

response = openai.Completion.create(

#print('--- Response payload: ---')

#print('--- Prompt: ---')

# parse the response payload dictionary and printout the output
print('--- Response text: ---')

Detailed article about possible model parameters:

Shell scipt takes the keywords from the file and spawns new python subprocess for each API call.
Wrapper makes sure we are not overwriting our previously captured data, since in general,
each API call costs money (above free tier).


# we expect the files to be in the same directory as the wrapper script
# to maintain consistency
# call like:
# ./openai_API/ openai_vocab.txt output1.txt

# input file with vocabulary should have following format
# we take only the first word on each line to pass to subprocess
#愛する|あいする|to love| | | |
#飽きる|あきる|to lose interest| | | |

set -eu

# Check if a file was provided as an argument
if [[ $# -lt 2 ]]
    echo "Error: No file provided"
    exit 1

# Get the current directory
current_dir=$(dirname $(readlink -f "$0"))

# Assign the file to a variable

# Check if the file already exists
if [ -e "$current_dir/$outfile" ]
    # Print an error message and exit
    echo "Error: File '$outfile' already exists in '$current_dir'"
    exit 1
    # Create the file
    touch "$current_dir/$outfile"

# Iterate through each line in the file
while read -r line
    # Extract the first word from the line
    first_word=$(echo "${line}" | awk -F'|' '{print $1}')

    # Print the first word
    #echo "${first_word}"

    #call python script with the word as argument and filter empty lines, appends to a file
    python3 "${current_dir}/" "${first_word}" | sed '/^$/d' | tee -a "${current_dir}/${outfile}"
    echo "-----------------------------" | tee -a "${current_dir}/${outfile}"
    # sleep so we do not overload the API
    sleep 5

done < "${current_dir}/${file}"

exit 0

Run the app with our shell wrapper as follows.

(.env) coil@coil-VM:~/Desktop/openai_API$ ./ openai_N3_tango_p172-191_verbs_1.txt output_openai_N3_tango_p172-191_verbs_1.txt
