If length of keys list is less than list of values then remaining elements in value list will be skipped. Convert a list of tuples to dictionary A sequence contains elements where each element allotted a value, i.e., its position or index. Lists and Tuples are used to store one or more Python objects or data-types sequentially. Tuples are used to store multiple items in a single variable. The values stored in a tuple can be any type, ... to another set of objects (values). So what's the difference between an array and a list in Python? 4. A tuple is data structure like an array, which is … A Python dictionary is a mapping of unique keys to values.
