Year 10 Computing — Text inside a program

Work out how many characters a piece of text holds, which character sits at a given position, and what joining two pieces of text end to end gives.

Name: ________________________

1.The same short piece of text is joined to itself twice over. What does this program print?
```
tag = "ab"
joined = tag + tag + tag
print(len(joined))
```
2.Two pieces of text are joined and the length of the result is printed. What does this program print?
```
a = "web"
b = "page"
print(len(a + b))
```
- a) 2
- b) 4
- c) 8
- d) 7
3.The text is the same for all of these. Match each line to what it prints.
```
word = "network"
```
- print(word[0])
- print(word[3])
- print(word[6])
- print(len(word))
- print(word[len(word) - 2])
- k
- r
- n
- 7
- w
4.Two pieces of text are joined end to end here and the result is printed. What does the program print?
```
first = "sun"
second = "rise"
print(first + second)
```
5.Look carefully at what is between the quote marks in this one. What does it print?
```
words = "two words"
print(len(words))
```
- a) 8
- b) 9
- c) 10
- d) 4
6.A character is read out of the joined text rather than out of either of the two pieces. What does this program print?
```
left = "top"
right = "most"
joined = left + right
print(joined[3])
```
7.This program starts with a piece of text holding nothing at all and joins something on to it each time round. What does it print?
```
line = ""
for n in range(0, 4):
    line = line + "ab"
print(len(line))
```
8.This one works out the last position for itself before reading a character from it. What does it print?
```
word = "screen"
print(word[len(word) - 1])
```
