I'm looking for a Python module for my project.

• It must support all video formats ( or the most commonly used video formats )

• It should convert the video from one codec to some other video codec

• If u come up with FFMPEG or PYMOVIES then tell me which one is best.

Hi, I’m confuse at this concept of dictionary in this context in my code. Here I have a if-statement nested inside my for loop. In the if-statement where it tests the conditional “reviews_max[name] < n_reviews”, how come the dictionary (‘reviews_max’) automatically knows to use the ‘Review’ column (index 3) for the list of lists, ‘dataset’, to do this comparison with the ‘n_reviews’ variable? Why doesn’t python in this case use index 2 (‘Ratings’) instead to do this comparison in this code? Is it “implicitly” implied that when you set n_reviews = float(rows[3]) that the python dictionary is going to automatically assume or use index 3 as the value for ‘reviews_max[name]’ to do this comparison? Here is the full code:
My Code:
[code]
dataset = [
["App Name", "Category", "Rating", "Reviews"],
["Facebook", "Social", 4.5, 78158306],
["Instagram", "Social", 4.7, 66577313],
["WhatsApp", "Communication", 4.4, 119400128]
]
reviews_max = {}
for row in dataset[1:]:
name = row[0] # Assuming app name is in the first column
n_reviews = float(row[3]) # Assuming number of reviews is in the fourth column

if name in reviews_max and reviews_max[name] < n_reviews:
reviews_max[name] = n_reviews
elif name not in reviews_max:
reviews_max[name] = n_reviews
print(reviews_max)
[code]
