| Operation | Result | Trans |
|---|---|---|
s[i] = x |
item i of s is replaced by x | |
s[i:j] = t |
slice of s from i to j is replaced by the contents of the iterable t | |
del s[i:j] |
same as s[i:j] = [] |
|
s[i:j:k] = t |
the elements of s[i:j:k] are replaced by those of t |
|
del s[i:j:k] |
removes the elements of s[i:j:k] from the list |
|
s.append(x) |
appends x to the end of the sequence (same as s[len(s):len(s)] = [x]) |
|
s.clear() |
removes all items from s (same as dels[:]) |
|
s.copy() |
creates a shallow copy of s (same as s[:]) |
|
s.extend(t) or s += t |
extends s with the contents of t (for the most part the same as s[len(s):len(s)]= t) |
|
s *= n |

s.insert(i, x) |
inserts x into s at the index given by i(same as s[i:i] = [x]) |
|
s.pop([i]) |
retrieves the item at i and also removes it from s | |
s.remove(x) |

|
s.reverse() |
reverses the items of s in place |
