【Python】利用pandas将数据写入csv表格

import pandas as pd

list = [1,2,3]#一维数据
df = pd.Series(list)
df.to_csv(r"C:\xxx\04.csv",mode ="a+",index=False,header=False)
#追加模式，去掉索引和表头

list2 = [[1,2,3],[11,12,13],[21,22,23],[31,32,33],[41,42,43],[51,52,53],]#多维数据
df1 = pd.DataFrame(list2)
df1.to_csv(r"C:\xxx\04.csv",mode ="a+",index=False,header=False)
