I am trying to save my images with the time epoch plus iterating integers like this:
text_img.save('/content/result/' + epoch + '_%03d' + '.png' , format="png")
However, the output is something like this:
16087965_%03d.jpg
The formatting does not work for some reason. I do not know why.
At the moment, '_%03d' is just a literal string. Since your code is in a loop, you'll want to provide the loop counter variable to be formatted.
Try something like:
import time
for i in range(100):
epoch = str(int(time.time() / 1000))
name = '/content/result/' + epoch + '_%03d' % i + '.png'
text_img.save(name, format='png')
Or you can instead achieve the same thing using f-strings:
import time
for i in range(100):
epoch = str(int(time.time() / 1000))
name = f'/content/result/{epoch}_{i:03}.png'
text_img.save(name, format='png')
epoch before the loop. I assume the point of the increasing integers is to distinguish files sharing the same timestamp.
%03d doesn't generate an integer itself, it only provides the "instruction" to the % operator for how to format an integer you provide. That is, %03d isn't special to the string, only to the % operator which parses the string in order to produce a new string.
_%03dsupposed to give?_001,_002, and so on
