Python使用Pandas读写Excel实例解析

pip3 install pandas
pip3 install xlrd
pip3 install openpyxl

import pandas as pd
from pandas import DataFrame

#写
dic1 = {'标题列1': ['张三','李四'],
    '标题列2': [80, 90]
    }
df = pd.DataFrame(dic1)
df.to_excel('1.xlsx', index=False)

pd.read_excel(io, sheet_name=0, header=0, names=None, index_col=None, 
       usecols=None, squeeze=False,dtype=None, engine=None, 
       converters=None, true_values=None, false_values=None, 
       skiprows=None, nrows=None, na_values=None, parse_dates=False, 
       date_parser=None, thousands=None, comment=None, skipfooter=0, 
       convert_float=True, **kwds)

import pandas as pd
from pandas import DataFrame

#读
data = pd.read_excel('1.xlsx')

#查看所有的值
print(data.values)

#查看第一行的值
print(data.values[0])

#查看某一列所有的值
print(data['标题列1'].values)

#新增列
data['标题列3'] = None

#新增行
data.loc[3] = ['王五', 100, '男']

#删除行：axis=0
data = data.drop([0,1], axis=0)

#删除列：axis=1
data.drop('标题列3', axis=1)

#保存
DataFrame(data).to_excel('1.xlsx', sheet_name='Sheet1', index=False, header=True)
