Formatting Operators

Question 1

Conversion type %d

Answer 1

Signed integer decimal

(same as %i but %d is used more often)

Question 2

Conversion %f

Answer 2

Floating point decimal format.

note: The alternate form causes the result to always contain a decimal point, even if no digits follow it.

The precision determines the number of digits after the decimal point and defaults to 6.

Question 2

Conversion %c

Answer 2

Single character (accepts integer or single character string).

Question 3

What is the fourth conversion specifier component

Answer 3

Minimum field width (optional). If specified as an “*” (asterisk), the actual width is read from the next element of the tuple in values, and the object to convert comes after the minimum field width and optional precision.

Question 4

Conversion %u

Answer 4

Unsigned decimal.

Question 5

Conversion %F

Answer 5

Floating point decimal format.

note: The alternate form causes the result to always contain a decimal point, even if no digits follow it.

The precision determines the number of digits after the decimal point and defaults to 6.

Question 5

Conversion %G

Answer 5

Floating point format. Uses exponential format if exponent is greater than -4 or less than precision, decimal format otherwise.

note: The alternate form causes the result to always contain a decimal point, and trailing zeroes are not removed as they would otherwise be.

The precision determines the number of significant digits before and after the decimal point and defaults to 6.

Question 6

What is the fifth conversion specifier component

Answer 6

Precision (optional), given as a “.” (dot) followed by the precision. If specified as “*” (an asterisk), the actual width is read from the next element of the tuple in values, and the value to convert comes after the precision.

Question 7

What is the second conversion specifier component

Answer 7

Mapping key (optional), consisting of a parenthesized sequence of characters (for example, (somename)).

Question 8

Conversion %

Answer 8

No argument is converted, results in a “%” character in the result.

Question 9

Conversion %o

Answer 9

Unsigned octal

note: The alternate form causes a leading zero (“0”) to be inserted between left-hand padding and the formatting of the number if the leading character of the result is not already a zero.

Question 10

What is the third conversion specifier component

Answer 10

Conversion flags (optional), which affect the result of some conversion types.

Question 12

Conversion %X

Answer 12

Unsigned hexadecimal (uppercase).

Question 13

Conversion %s

Answer 13

String (converts any python object using str()).

note: If the object or format provided is a unicode string, the resulting string will also be unicode.

The precision determines the maximal number of characters used.

Question 15

How many possible values can a conversion specifier have

Answer 15

7 (They MUST be in order)

Question 16

Conversion %e

Answer 16

Floating point exponential format (lowercase).

note: The alternate form causes the result to always contain a decimal point, even if no digits follow it.

The precision determines the number of digits after the decimal point and defaults to 6.

Question 17

Conversion %x

Answer 17

Unsigned hexadecimal (lowercase).

Question 18

Conversion %E

Answer 18

Floating point exponential format (uppercase).

note: The alternate form causes the result to always contain a decimal point, even if no digits follow it.

The precision determines the number of digits after the decimal point and defaults to 6.

Question 19

Conversion type %i

Answer 19

Signed integer decimal

Question 20

Conversion %r

Answer 20

String (converts any python object using repr()).

The %r conversion was added in Python 2.0.

The precision determines the maximal number of characters used.

Question 21

Conversion %g

Answer 21

Floating point format. Uses exponential format if exponent is greater than -4 or less than precision, decimal format otherwise.

note: The alternate form causes the result to always contain a decimal point, and trailing zeroes are not removed as they would otherwise be.

The precision determines the number of significant digits before and after the decimal point and defaults to 6.

Question 22

What is the sixth conversion specifier component

Answer 22

Length modifier (optional).

Question 23

What is the first conversion specifier component

Answer 23

1. The “%” character, which marks the start of the specifier.

Question 24

What is the seventh conversion specifier component

Answer 24

Conversion type.
