Python中的Series模块学习
Python中的Series模块学习
本文是基于Windows系统环境，学习和测试Series模块：
-
Windows 10
-
PyCharm 2018.3.5 for Windows (exe)
-
python 3.6.8 Windows x86 executable installer
1. 增改删查
- 初始化一个Series
from pandas import Series
info = Series([13, 'rose', True], index=['age', 'name', 'isStudent'])
info1 = Series([13, 'rose', True])
print(info)
print(info1)
- 向Series插入一个元素
from pandas import Series
info = Series([13, 'rose', True], index=['age', 'name', 'isStudent'])
print(info)
info = info.append(Series(['female'],index=['gender']))
info1 = info.append(Series(['female']))
print(info)
- 删除Series的一个元素
from pandas import Series
info = Series([13, 'rose', True], index=['age', 'name', 'isStudent'])
print(info)
info.drop('name')
print(info)
- 查询值不为某个特定值的元素
from pandas import Series
info = Series([13, 'rose', True], index=['age', 'name', 'isStudent'])
print(info)
info1 = info[13 != info.values]
info2 = info['rose' != info.values]
info3 = info[True != info.values]
print(info1)
print(info2)
print(info3)
2. 遍历
- 遍历所有的的索引和索引值
from pandas import Series
info = Series([13, 'rose', True], index=['age', 'name', 'isStudent'])
print(info)
for index in info.index:
print(index, '=', info[index])
