Formatting API List with for loop in a Table

I want to output a list I get from the API in a table so it looks nicer. The data from the API is returned with a for loop. My problem now is that I don't know how to get it that the header isn't looped every time.

for Example:

And i want one header and the rest under the header

I have managed with some instructions from here that the data will be displayed with "Tabulate" at all in a table. However, the "header" will be inserted at each run again.

head = ["Datum", "Username", "License Server", "Feature Name", "Max. Usage", "Hours Used", "Max Used", "Hours Borrowed", "Max Borrowed"]

for item in (data['data'])
   if item['un'] == tecNo:
      print(tabulate([[item['fud'], item['un'], str(item['lsn']), str(item['fns']), str(item['musage']), str(item['hu']), str(item['mu']), str(item['hb']), str(item['mb'])]],headers=head, tablefmt="grid"))```

Solution

You need to put the items in a 2d array, then call tabulate at the end.

table = []
for item in (data['data'])
   if item['un'] == tecNo:
      table.append([
          item['fud'], 
          item['un'], 
          str(item['lsn']), 
          str(item['fns']), 
          str(item['musage']), 
          str(item['hu']), 
          str(item['mu']), 
          str(item['hb']), 
          str(item['mb'])
      ])
tabulate(table, headers=head)
