# Python: Convert in feet to inches, yards, and miles

## Python Basic: Exercise-61 with Solution

Write a Python program to convert the distance (in feet) to inches, yards, and miles.

Unit Equivalents Conversion Factors
(longer to shorter units of measurement)
Conversion Factors
(shorter to longer units of measurement)
1 foot = 12 inches 12 inches
_______
1 foot
1 foot
_______
12 inches
1 yard = 3 feet 3 feet
_______
1 yard
1 yard
_______
3 feet
1 mile = 5,280 feet 5,280 feet
________
1 mile
1 mile
________
5,280 feet

Pictorial Presentation: Sample Solution:

Python Code :

``````d_ft = int(input("Input distance in feet: "))
d_inches = d_ft * 12
d_yards = d_ft / 3.0
d_miles = d_ft / 5280.0

print("The distance in inches is %i inches." % d_inches)
print("The distance in yards is %.2f yards." % d_yards)
print("The distance in miles is %.2f miles." % d_miles)
```
```

Sample Output:

```Input distance in feet: 100
The distance in inches is 1200 inches.
The distance in yards is 33.33 yards.
The distance in miles is 0.02 miles.
```

## Python: Tips of the Day

Kwargs:

**kwargs and *args are function arguments that can be very useful.

They are quite underused and often under-understood as well.

Let's try to explain what kwargs are and how to use them.

• While *args are used to pass arguments at an unknown amount to functions, **kwargs are used to do the same but with named arguments.
• So, if *args is a list being passed as an argument, you can think of **kwargs as a dictionary that's being passed as an argument to a function.
• You can use arguments as you wish as long as you follow the correct order which is: arg1, arg2, *args, **kwargs. It's okay to use only one of those but you can't mix the order, for instance, you can't have: function(**kwargs, arg1), that'd be a major faux pas in Python.
• Another example: You can do function(*args,**kwargs) since it follows the correct order.
• Here is an example. Let's say satelites are given with their names and weight in tons in dictionary format. Code prints their weight as kilograms along with their names.
```def payloads(**kwargs):
for key, value in kwargs.items():
print( key+" |||", float(value)*100)
payloads(NavSat1 = '2.5', BaysatG2 = '4')
```

Output:

```NavSat1 ||| 250.0
BaysatG2 ||| 400.0```

Since the function above would work for any number of dictionary keys, **kwargs makes perfect sense rather than passing arguments with a fixed amount.

```def payloads(**kwargs):
for key, value in kwargs.items():
print( key+" |||", float(value)*100)

sats={"Tx211":"3", "V1":"0.50"}
```Tx211 ||| 300.0
