Basic api_url() function

### Description

The function must accept the variables needed to compose a URL and produce a string containing a full URL to connect to the API.

Input parameters should be:

- base URL
- endpoint (e.g. csv, meta, get query, post query, summary, publications, data version)
- API version
- data set ID
- data set version

Should need to use some if logic and then concatenation to combine the variables.

The function will then output the completed URL, allowing users to reach their endpoint.

### Why this is important?

Code for a solution I made in Python:

#List of imports used.
import time
import sys

#Variable declaration

base_url = 'https://api.education.gov.uk/statistics/'
api_version = 'v1'
dataset_id = '63629501-d3ca-c471-9780-ec4cb6fdf172'
data_set_version = '1.0'

def main():
print('Welcome!')
time.sleep(0.5)

while True:

endpoint = input('Please enter endpoint: ').lower() #Asks the user to enter the endpoint of the URL.

#Selection statements relative to the entered endpoint

if endpoint == 'csv':
csv()
False

elif endpoint == 'meta':
meta()
False

elif endpoint == 'query':
query()
False

elif endpoint == 'summary':
summary()
False

else:
print('Please enter a valid response.')
True

def csv():

total_url = base_url + api_version + '/data-sets/' + dataset_id + '/csv?datasetVersion=' + data_set_version #Concatenates the URL elements to form a full URL.
end(total_url)

def meta():

total_url = base_url + api_version + '/data-sets/' + dataset_id + '/meta?datasetVersion=' + data_set_version #Concatenates the URL elements to form a full URL.
end(total_url)

def query():
total_url = base_url + api_version + '/data-sets/' + dataset_id + '/query?datasetVersion=' + data_set_version #Concatenates the URL elements to form a full URL.
end(total_url)

def summary():
total_url = base_url + api_version + '/data-sets/' + dataset_id #Concatenates the URL elements to form a full URL.
end(total_url)

def end(url):
time.sleep(0.5)
print(f'The URL linked to your endpoint is: {url}') #Prints out the concatenated URL
time.sleep(0.5)
while True:
repeat = input('Would you like to run the program again (y/n)?').lower() #Asks the user if they would like to repeat the code

#If the user enters 'y' (yes) the code repeats from the beginning.
if repeat == 'y':
print('Repeating...')
time.sleep(0.5)
main()
False
#If the user enters 'n' (no) the code ends and will not repeat.
elif repeat == 'n':
print('exiting the program.')
sys.exit()

#If the user does not enter 'y' or 'n', requests that the user enters a valid response, repeats the question.
else:
print('Please enter a valid response.')
True
