前幾天，項(xiàng)目中有個小需求：提供Excel的上傳下載功能，使用模塊：openpyxl 和 xlsxwriter，這里簡單記錄一下。
1.簡介
Python中操作Excel的庫非常多，為開發(fā)者提供了多種選擇，如：xlrd、 xlwt、xlutils、xlwings、pandas、 win32com、openpyxl、xlsxwriter等等。
其中：
前三個一般混合使用，對Excel讀寫操作，適合舊版Excel，僅支持 xls 文件；
win32com 庫功能豐富，性能強(qiáng)大，適用于Windows；xlwings稍次于前者，但同樣功能豐富；pandas適合處理大量數(shù)據(jù)；xlsxwriter 適合大量數(shù)據(jù)的寫操作，支持圖片/表格/圖表/篩選/格式/公式等；openpyxl 讀寫均可，簡單易用，功能廣泛，可插入圖表等，類似前者。
以下主要描述一下后兩種（openpyxl、xlsxwriter）的簡單使用

2.1.目標(biāo)
2.2.openpyxl的使用
2.2.1.安裝
2.2.2.寫入Excel

def write_test():
wb = Workbook()
filename = FILE_PATH + '/openpyxl_test.xlsx'
# 活動sheet
ws1 = wb.active
ws1.title = "Test-1"
# 列表追加
for row in range(1, 10):
ws1.append(range(9))
# 創(chuàng)建sheet
ws2 = wb.create_sheet(title="Test-2")
# 合并單元格
ws2.merge_cells('F5:I5')
# 拆分
# ws2.unmerge_cells('F5:I5')
# 單元賦值
ws2['F5'] = 'hello world'
# 居中

# 背景顏色
bg_color = PatternFill('solid', fgColor='1874CD')
ws2['F5'].fill = bg_color
# 行高列寬
ws2.row_dimensions[5].height = 40 # 第 5 行
ws2.column_dimensions['F'].width = 30 # F 列

for row in range(10, 20):
for col in range(10, 20):
ws3.cell(column=col, row=row, value="0}".format(get_column_letter(col)))
print(ws3['S10'].value)
# 保存
wb.save(filename)
2.2.3.讀取Excel
from openpyxl import load_workbook
def read_test(filename):
wb = load_workbook(filename)
print('取得所有工作表的表名 :')
print(wb.sheetnames, '\n')
print('取得某張工作表 :')
# sheet = wb['Sheet1']
# sheet = wb.worksheets[0]
sheet = wb[wb.sheetnames[0]]
print(type(sheet))
print('表名: ' + sheet.title, '\n')
print('取得活動工作表 :')
active_sheet = wb.active
print('表名: ' + active_sheet.title, '\n')
print('獲取工作表的大小:')
print('總行數(shù): ' + str(active_sheet.max_row))
print('總列數(shù): ' + str(active_sheet.max_column))
print('\n獲取單元格數(shù)據(jù):')
for row in range(sheet.max_row):
for col in range(sheet.max_column):
print(f"第 {row + 1} 行 {col + 1} 列：", sheet.cell(row=row + 1, column=col + 1).value)
print('\n獲取行數(shù)據(jù):')
for i, cell_object in enumerate(list(sheet.rows)):
cell_lst = [cell.value for cell in cell_object]
print(f'第 {i + 1} 行：', cell_lst)
