CHAPTER8: STRINGS AND FUNCTION IN PYTHON

CHOOSE THE CORRECT ANSWER:-

1 []

2 ()

3 FUNCTION

4 \

5 DEF

STATE TRUE OR FALSE

1 FALSE

2 FALSE

3 FALSE

4 TRUE

5 TRUE

FILL IN THE BLANKS:-

1 RETURN

2 LEN(STRING)

3 IN

4 FUNCTION

5 UPPER()

ANSWER THE FOLLOWING QUESTIONS:-

ANS1:-An escape sequence is a non-printable chahracter.It is written

using a backslash(\) followed by the chahracter.

\n-- Here n is known as the new line character,displays the text in new

line.

\ \ ---it is used to print a backslash

\` It is used to print an apostraphe

\” It is used to print double quotation marks.

\t It is used to add horizontal tab space between text.

\vIt is used to add vertical tab space.

Ans2-A function is a group of realted statement that perform a specific

task.It makes the program more readable as it organize statement.Afunction is given a name that makes it easy to use the function.Once a

function is defined, the user will be able to perform that task by its name

and not by the steps involved to accomplish it.

Ans 3- There are some built in function in Python,which can be directly

used to perform some specific task.

1-capitalize() .it change the first letter of a string in capital form .

example- ”computer”.capitalize()>>Computer

2- isdigit(), It return True if string has at least one character and all

chahacter are digits.Example “123”.isdigit()>>true

3- Islower(), It return True if string has at least one chahacter and all

chahacter are in lower case.Example “hello”.islower()>>true

4- Len(string), It is used to find out the length of a string.Example

len(“Python”)>>6

5- Upper() , It converts lower case letters into upper case.Example

“python”.upper()>>PYTHON

Ans 4- A return statement is used to end the execution of the function

call and returns the result,which can be any expression or calculated

value.The statement after return statements are not executed.

Ans 5-

def greater(a,b):

If (a>b):

return a

else:

return b

big=greater(40,15)

print(big)

1) is right
