How to put a function inside VideoFileClip ()?

Question

In my current directory I have a file.mp4.

Problem:
I want to search the name of that file and then put file.mp4 in the VideoFileClip('file.mp4').

How can I do that? I get an error when I run the code below, because VideoFileClip() accepts only String. How can we put search function inside a function?

My code:

from glob import glob
from moviepy.editor import VideoFileClip

clip = VideoFileClip(glob("*.mp4"))
s = clip.duration
clip.close() 

I also tried replacing:

clip = VideoFileClip( glob("*.mp4") )

with this alternative:

clip = VideoFileClip( str(glob("*.mp4")) )

"How can we put search function inside a function"

You don't put a "search function inside a function".

• First you get the result of a search function (put it into a variable).
• Then you use that same result (the variable) as the input of some other function.

See if a code logic like below is closer to achieving what you want (ps: code is untested):

import glob
from moviepy.editor import VideoFileClip

## Glob gives back an Array (is a list with String for each file's name)
file_list = glob.glob("*.mp4")
print("found MP4 file(s) :", file_list)

## From the Array list, now select the specific String you want to use with some function
## Test by getting the first filename's String (is at position 0 inside the list)
my_file_str = file_list[0]
print("Using this file String :", my_file_str)

clip = VideoFileClip( my_file_str)
sec = clip.duration
print("sec (clip.duration) :", sec, "seconds")
clip.close()
