Python creates a fixed length empty list

python There are two ways to create an empty list of fixed length

Method 1

a = 10
x = [’’ for i in range(a)]
print(x)
#[’’, ‘’, ‘’, ‘’, ‘’, ‘’, ‘’, ‘’, ‘’, ‘’]

Method 2

a = 10
x = [None]*a
print(x)
#[None, None, None, None, None, None, None, None, None, None]

Notice the difference between the two methods , One is an empty character , One is None
