Python: My Fake Data Generator P-7



Learning : Python: Functions, Procedures and documentation
Subject: About fake data P-7: (Fake File Name)

In this post we will write a function to generate a file name. Each file name consist of two part, first one is the name which present (or should present) a meaning part, then there is a dot (.) then mostly three characters showing the file type or extension.

Scope of work: Our files names will have 4 syllables all to gather will be one file name. Each syllables will be loaded in a variable as shown ..
1. fext: for Files extensions such as: (doc, jpeg, pdf, bmp …. and so on)
2. name_p1: Is a noun such as (customers, visitors, players .. . and so on )
3. name_p2: will be an nouns, adjective or characteristics such as (name, index, table .. .. and so on)
4. Then we will add a random integer number between (1,30) to give the file a version, or a number.

All parts or syllables will be as one file name.

Let’s Work: First we need to load the File name syllables from the json file called : file_dict.json

 # Loading the json from a url 

import json , requests, random

fname = "https://raw.githubusercontent.com/Ali-QT/Ideas-and-Plan/master/file_dict.json"

def call_json_url(fname):
    """
    Function to load the json file from URL.
    Argument: str :fname
    
    Return : dict: data
    """
    req = requests.get(fname)
    cont = req.content
    data = json.loads(cont)
    return data

fdict = call_json_url(fname)

# Save each syllables into variable. 
f_ext = fdict["fext"]
f_p1_name = fdict["name_p1"]
f_p2_name = fdict["name_p2"]


Now we will write the function that will generate the file name:

 # Function to generate the file name 

def generate_fname():
    """
    Function to generate a Fake files name.
    
    File Name consist of four syllables, Two names, a random number and an extension.
    First two syllables of the file name will be selected randomly from a dictuenary stored in a json       file.
    
    Return : str : f_file_name

    To read the information key in the json file use this code.
    ------ CODE TO READ DATA-SET INFORMATION --------------
     	for each in fdict["information"]:
          print(each,":",fdict["information"])

    ---END OF CODE ------------------------------------------
    """
    fp1 = (random.choice (f_p1_name)["n_p1"])
    fp2 = (random.choice (f_p2_name)["n_p2"])
    fp3 = (random.choice (f_ext)["ext"])

    f_file_name = (fp1 + "_" + fp2 + "_" + str(random.randint(1,30)) + "." + fp3)

    return f_file_name


Last thing we just will call the function for X numbers of files Name we want.

 # Generate 15 file Name. 

for x in range (15):
    generate_fname()

[Output]:
