B)  The names of c's elements are c[0], c[1], c[2], c[3] and c[4]. 
C)  The length of c is 5. 
D)  All of the above statements are true.

Accepted Answer

A)  parallel 
B)  heterogeneous

Question 5

Which of the following statements a), b) or c) is false?

Accepted Answer

A)  You can xe "sequence:concatenate"xe "concatenate sequences"concatenate two lists, two tuples or two strings using the xe "sequence:+ operator for concatenation"xe "+ operator for sequence concatenation"+ operator. The result is a new sequence of the same type containing the left operand's elements followed by the right operand's elements. 
B)  A TypeError occurs if the + operator's operands are different sequence types-for example, concatenating a list and a tuple is an error. 
C)  List elements can be accessed via their indices and the subscription operator ([]). 
D)  All of the above statements are true.
