2. remove method – list.remove(list[index])

4. slicing – list[1:]

# Python code to understand how to drop first element of the list
# www.codewindow.in
 
a = [10, 11, 12, 13, 14]
b = [10, 11, 12, 13, 14]
c = ['a', 's', 'd', 'f']
d = ["code", "window", "repeat"]
 
 
#using pop method
a.pop(0)
print(a)
 
#using remove method
b.remove(b[0])
print(b)
 
#using del method
del c[0]
print(c)
 
#using slicing
d = d[1:]
print(d)

Output:

[11, 12, 13, 14]
[11, 12, 13, 14]
['s', 'd', 'f']
["window", "repeat"]

Explanation:
Here, pop(0) pops the first element from the list.
remove(b[0]) removes the element indexed at 0 i.e. the first element.
del c[0] deletes the first element indexed at 0 i.e. the first element.
d[ 1:] slices the array from index 1 leaving the first element at index 0.
