 # LPTHW – Exercise 5 More Variables and Printing

LEARN PYTHON THE HARD WAY- Chapter 5 Exercise

```my_name = 'Zed A. Shaw'
my_age = 35 # not a lie
my_height = 74 # inches
my_weight = 180 # lbs
my_eyes = 'Blue'
my_teeth = 'White'
my_hair = 'Brown'

print "Let's talk about %s." % my_name
print "He's %d inches tall." % my_height
print "He's %d pounds heavy." % my_weight
print "Actually that's not too heavy."
print "He's got %s eyes and %s hair." % (my_eyes, my_hair)
print "His teeth are usually %s depending on the coffee." % my_teeth

# this line is trick, try to get it exactly right
print "If I add %d, %d, and %d, I get %d." % (my_age, my_height, my_weight, my_age + my_height + my_weight)

```

LEARN PYTHON THE HARD WAY – Study Drills

### 1. Change all the variables so there is no my_ in front of each one. Make sure you change the name everywhere, not just where you used = to set them.

```name = 'Zed A. Shaw'
age = 35 # not a lie
height = 74 # inches
weight = 180 # lbs
eyes = 'Blue'
teeth = 'White'
hair = 'Brown'

print "Let's talk about %s." % name
print "He's %d inches tall." % height
print "He's %d pounds heavy." % weight
print "Actually that's not too heavy."
print "He's got %s eyes and %s hair." % (eyes, hair)
print "His teeth are usually %s depending on the coffee." % teeth

# this line is a trick, try to get it exactly right
print "If I add %d, %d, and %d, I get %d." % (age, height, weight, age + height + weight)```

## 2. Try to write some variables that convert the inches and pounds to centimeters and kilograms. Do not just type in the measurements. Work out the math in Python.

```name = 'Zed A. Shaw'
age = 35 # not a lie
height = 74 # inches
weight = 180 # lbs
eyes = 'Blue'
teeth = 'White'
hair = 'Brown'

cm_height = height * 2.54
kg_weight = weight * 0.453592

print "Let's talk about %s." % name
print "He's %d centimeters tall." % cm_height
print "He's %d kilograms heavy." % kg_weight
print "Actually that's not too heavy."
print "He's got %s eyes and %s hair." % (eyes, hair)
print "His teeth are usually %s depending on the coffee." % teeth

# this line is trick, try to get it exactly right
print "If I add %d, %d, and %d, I get %d." % (age, cm_height, kg_weight, age + cm_height + kg_weight)```

## 3. Search online for all of the Python format characters.

```# 'd' Signed integer decimal.
# 'i' Signed integer decimal.
# 'o' Signed octal value.
# 'u' Obsolete type – it is identical to 'd'.
# 'e' Floating point exponential format (lowercase).
# 'E' Floating point exponential format (uppercase).
# 'f' Floating point decimal format.
# 'F' Floating point decimal format.
# 'g' Floating point format. Uses lowercase exponential format if exponent is less than -4 or not less than precision, decimal format otherwise.
# 'G' Floating point format. Uses uppercase exponential format if exponent is less than -4 or not less than precision, decimal format otherwise.
# 'c' Single character (accepts integer or single character string).
# 'r' String (converts any Python object using repr()).
# 's' String (converts any Python object using str()).
# '%' No argument is converted, results in a '%' character in the result.```
