Python_01_problemset 

1.  Start up the Python Interactive Interpreter. Print out "Hello New York"

pfb14:~ admin$ python3

Python 3.6.2 |Anaconda, Inc.| (default, Sep 21 2017, 18:29:43) 
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

>>>print("Hello New York")

2.  Store your name in a variable and print the contents of this variable.

>>> variable1=sabriya
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'sabriya' is not defined
>>> variable1 = "sabriya"

>>> print(variable1)
sabriya

#variable1 points to a string (= sabriya)





3.  Use nano to write a script. Make sure to include # !/usr/bin/env python3 at the top!!
The script should print out, your name, favorite color, favorite activity, and your favorite animal.
Make it executable using chmod (only have to do this one time per script).
Run it from the command line.

pfb14:Python2017_problemsets admin$ nano myscript_1.py

in nano

#!/usr/bin/env python3

print("sabriya") #name
print("green") #favorite color
print("eating") #favorite activity
print("cat") #favorite animal



pfb14:Python2017_problemsets admin$ ls -l myscript_1.py 
-rw-r--r--  1 admin  staff  144 Oct 17 11:14 myscript_1.py
pfb14:Python2017_problemsets admin$ chmod +x myscript_1.py
pfb14:Python2017_problemsets admin$ ls -l myscript_1.py 
-rwxr-xr-x  1 admin  staff  144 Oct 17 11:14 myscript_1.py

pfb14:Python2017_problemsets admin$ python3 myscript_1.py

pfb14:Python2017_problemsets admin$ ./myscript_1.py

4. Use sys.argv (make sure to import sys!!!) to retrieve your name, favorite color, favorite activity, and favorite animal from the command line.

pfb14:Python2017_problemsets admin$ nano myscript_2.py


#!/usr/bin/env python3
import sys

a= sys.argv[str(sabriya)] #name
b= sys.argv[str(green)] #favorite color
c= sys.argv[str(eating)] #favorite activity
d= sys.argv[str(cats)] #favorite animal

print(a,b,c,d) #print a,b,c,d strings
