I Consider Myself An Intermediate Programmer (casual programmer) But Never Unpacked An Iterable. Share Me Your Best Thought!

Why To Unpack An Iterable?

What Is The Usecase Of Unpacking?

When Shall I Unpack?

Is It Only For This :

PROGRAM1_INPUT :
data = [
("filename1.txt", 1024),
("filename2.txt", 2048),
("filename3.txt", 512)
]

for name, size in data:
print(name, "is", size, "bytes")

PROGRAM1_OUTPUT :
filename1.txt is 1024 bytes
filename2.txt is 2048 bytes filename3.txt is 512 bytes

PROGRAM2_INPUT :
k, l, *i, x = range(20)

print(k) 
print(l) 
print(i)  
print(x)
