Python读取Excel数据代码

使用Python读取Excel数据需要用到第三方库，常用的有xlrd、openpyxl和pandas等。以下是使用xlrd库读取Excel数据的示例代码：

import xlrd

# 打开Excel文件
workbook = xlrd.open_workbook('example.xlsx')

# 获取所有sheet名称
sheet_names = workbook.sheet_names()
print(sheet_names)

# 根据sheet索引或名称获取sheet内容
sheet1 = workbook.sheet_by_index(0)
sheet2 = workbook.sheet_by_name('Sheet2')

# 获取sheet的行数和列数
num_rows = sheet1.nrows
num_cols = sheet1.ncols

# 遍历每一行数据
for i in range(num_rows):
    row_values = sheet1.row_values(i)
    print(row_values)

使用openpyxl库读取Excel数据的示例代码：

from openpyxl import load_workbook

# 打开Excel文件
workbook = load_workbook(filename='example.xlsx')

# 获取所有sheet名称
sheet_names = workbook.sheetnames
print(sheet_names)

# 根据sheet名称获取sheet内容
sheet1 = workbook['Sheet1']
sheet2 = workbook['Sheet2']

# 获取sheet的行数和列数
num_rows = sheet1.max_row
num_cols = sheet1.max_column

# 遍历每一行数据
for row in sheet1.iter_rows(min_row=1, max_row=num_rows, values_only=True):
    print(row)

使用pandas库读取Excel数据的示例代码：

import pandas as pd

# 读取Excel文件中的Sheet1
df = pd.read_excel('example.xlsx', sheet_name='Sheet1')

# 获取所有行和列
rows, cols = df.shape

# 遍历每一行数据
for i in range(rows):
    row_values = df.loc[i].values.tolist()
    print(row_values)
