Manipulating Strings:
– `stringV = list(stringV)`: Converts a string into a list, with each character as a separate element.
– `stringV.split()`: Splits a string into words, separated by spaces.
– `Stringv.split(“_”)`: Divides a string into parts using underscores as delimiters.
– `S = ” “.join(Stringv)`: Adds spaces between words in a string.
Nested Lists:
– `allLists = [List1, list2, list3, list4, list5, list6]`: Creates a list containing nested lists.
– `allLists[0][0]`: Accesses the first element of the first list.
– `allLists[-3][-3][-1]`: Accesses elements using negative indexing.
– `allLists[index].append(“something”)`: Inserts an element into a nested list.
– `Length = len(nestedLists)`: Counts nested lists as one element.
– `Length = len(nestedLists[index][index])`: Counts elements within nested lists.
– `for item in nestedList: print(item)`: Iterates over all items in the nested list and prints them.
Objects and Values
– `id(x)`: Prints the memory position of an object.
– `print(a is b)`: Returns True if two variables point to the same object.
– `def delete(listN): del listN[0]`: Deletes the first element of a list.
