# Import pandas
import pandas as pd

# 读取csv文件
pd.read_csv("filename.csv")

# 导入 Pandas 库
import pandas as pd

pd.read_csv(filepath_or_buffer = "pokemon.csv")

# 使传递的行标题
pd.read_csv("pokemon.csv", header =[1, 2])

# 将传递的列作为索引而不是 0、1、2、3....
pd.read_csv("pokemon.csv", index_col ='Type')

# 仅将传递的 cols 用于数据框
pd.read_csv("pokemon.csv", usecols =["Type"])

# 如果只有一列，则返回熊猫系列
pd.read_csv("pokemon.csv", usecols =["Type"], squeeze = True)
							
# 跳过新系列中传递的行
pd.read_csv("pokemon.csv", skiprows = [1, 2, 3, 4])
