Python Introduction: A few more things

Getting help:

1) Use TAB in Jupyter or a quesiton mark

In [1]:
a = [1,2,3]
a?

2) Using pydoc3 on the command line.

3) Online at http://docs.python.org/

A few things to look up in a quiet moment

String formatting

In [2]:
"My name is {0} and I like {1}".format("Andreas", "hiking")
Out[2]:
'My name is Andreas and I like hiking'

or

In [3]:
"My name is %s and I like %s" % ("Andreas", "hiking")
Out[3]:
'My name is Andreas and I like hiking'

Dictionaries have key:value pairs of any Python object:

In [4]:
prices = {"Tesla K40": 5000, "GTX Titan":1400}
prices["Tesla K40"]
Out[4]:
5000
