Question

What is the missing line of code?

>>> phrase = "You are amazing!"
>>> _____
'u a'

phrase[3:6]

phrase[2:6]

phrase[3:5]

phrase[2:5]

Answer 1

Answer:

phrase[2:5]

Explanation:

Given:

The above code segment

Required

Which instruction returns 'u a'

First, we need to get the index of u in the phrase:

u is at the third position but in programming, index starts at 0.

So, u is at index 2

Next, we need to get the index of a in the phrase:

a is at index 4

One of the ways to return a sub string from a string in python is $string[start:stop+1]$

Where:

$start = 2$ ----- index of u

$stop = 4$  ----- index of a

phrase ---- The string variable

So, the instruction that returns 'u a' is: $phrase[2:5]$

Where 5 = 4 + 1
