Python basics

• Variable 은 letter 혹은 _로 시작해야 함. 즉 2a 와 같이 숫자가 먼저 오면 에러가 발생함.

Chained operation

In [1]: 1 < 2 < 3
Out[1]: True


In [2]: 1 < 2 > 3
Out[2]: False

Dictionary

• Dictionary comprehension

In [18]: d = {"a": 1, "b": 2, "c": 3}


In [19]: d = dict((key, value) for key, value in d.items() if value <= 1)


In [20]: print(d)
{'a': 1}

• dictionary.items() : key : value

for key, value in d.items():
	XXX

Math

• from math import pi

pprint

• from pprint import pprint

# print(d)
{'a': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 'b': [11, 12, 13, 14, 15, 16, 17, 18, 19, 20], 'c': [21, 22, 23, 24, 25, 26, 27, 28, 29, 30]}

# print(d)
{'a': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
 'b': [11, 12, 13, 14, 15, 16, 17, 18, 19, 20],
 'c': [21, 22, 23, 24, 25, 26, 27, 28, 29, 30]}
