list are mutable? |
True |
|
|
alist = ['a', 'd', 'f'] alist[1:1] = ['b', 'c'] print(alist) |
['a', b', 'c', 'f'] |
|
|
a = ['one', 'two', 'three'] del a[1] print(a) |
['one', 'three'] |
|
|
a = [81,82,83] b = a print(a is b) |
true |
|
|
a = [81,82,83] b = a[:] print(a is b) |
False |

How do you find the max number in a list? |
max(listA) min(listA) |
|
|
a = ['a', 'b', 'c', 'a'] a.remove('a') print(a) a.sort() print(a) |
['b', 'c', 'a'] ['a', 'b', 'c'] |
|
