1、创建一个DataFrame
import pandas as pd
import numpy as np
if __name__ == '__main__':
t1=pd.DataFrame(np.arange(12).reshape(3,4))
print(t1)
替换索引名称:
t2=pd.DataFrame(np.arange(12).reshape(3,4),index=list('abc'),columns=list('abcd'))
print(t2)
通过字典创建:
'''
通过字典创建
'''
p1={"name":['zhangsan','xiaoming'],"age":[19,21],"tel":[10086,10010]}
print(pd.DataFrame(p1))
通过列表创建:
'''
通过列表创建
'''
p2=[{'name':'zhangsan','age':19,'tel':10086},{'name':'xioaming','age':21,'tel':10010}]
print(pd.DataFrame(p2))
