python從excel中讀取數據
㈠ python怎麼從excel讀取數據
本程序需要導入xlrd包，可讀取後綴名為.xls和.xlsx的Excel文件，使用示例如下：
import xlrd
def read(file, sheet_index=0):
"""
:param file: 文件路徑
:param sheet_index: 讀取的工作表索引
:return: 二維數組
"""
workbook = xlrd.open_workbook(file)
# all_sheets_list = workbook.sheet_names()
# print("本文件中所有的工作表名稱:", all_sheets_list)
# 按索引讀取工作表
sheet = workbook.sheet_by_index(sheet_index)
print("工作表名稱:", sheet.name)
print("行數:", sheet.nrows)
print("列數:", sheet.ncols)
# 按工作表名稱讀取數據
# second_sheet = workbook.sheet_by_name("b")
# print("Second sheet Rows:", second_sheet.nrows)
# print("Second sheet Cols:", second_sheet.ncols)
# 獲取單元格的數據
# cell_value = sheet.cell(1, 0).value
# print("獲取第2行第1列的單元格數據:", cell_value)
data = []
for i in range(0, sheet.nrows):
data.append(sheet.row_values(i))
return data
if __name__ == '__main__':
print(read('工作簿1.xlsx'))
㈡ 用python讀取excel，怎樣顯示要查找的數據
感覺還是CSV格式的好處理一些，EXCEL的要裝插件，以CSV為例，給一段代碼
sqlserver char 對應c#
import linecache
o=open('d:\\test\\14.csv')#文件路徑
o.seek(0)
r=o.readlines()
s1=str(input('輸入要定位的信息:'))
a=0
count=0
for i in r: #按和值組合查找
if i.find(s1)>=0:
print r[a-1]#顯示上一行
print i#顯示定位行
print r[a+1]#顯示下一行
a+=1
print 'Total:%d'%count
例：
在以下數據中，查找含有T的行，並顯示上一行（n行） or 下一行（n行) 。
1，2，3，4
W,R,GFR,T
12,,F,34,G
㈢ python 如何讀取 excel 指定單元格內容
1、首先打開電腦上編寫python的軟體。
㈣ Python 如何讀取excel中的字典數據
import json
data_str = "AD列的值「
data = json.loads(data_str)
至於怎麼讀取excel中的數據：
import win32com.client as win32 # 安裝pywin32
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open('workbook1.xlsx')
sht = wb.Worksheets("Sheet1")
㈤ python怎麼從excel中讀取數據
#導入包
import xlrd
#設置路徑
path='C:\Users\jyjh\Desktop\datap.xlsx'
#打開文件
data=xlrd.open_workbook(path)
㈥ 如何通過Python實現Excel文件讀寫
參考代碼如下：
# -*- coding: utf-8 -*-
import xdrlib ,sys
import xlrd
def open_excel(file= 'file.xls'):
try:
data = xlrd.open_workbook(file)
return data
except Exception,e:
print str(e)
#根據索引獲取Excel表格中的數據 參數:file：Excel文件路徑 colnameindex：表頭列名所在行的所以 ，by_index：表的索引
def excel_table_byindex(file= 'file.xls',colnameindex=0,by_index=0):
data = open_excel(file)
table = data.sheets()[by_index]
nrows = table.nrows #行數
ncols = table.ncols #列數
colnames = table.row_values(colnameindex) #某一行數據
list =[]
for rownum in range(1,nrows):
row = table.row_values(rownum)
if row:
app = {}
for i in range(len(colnames)):
app[colnames[i]] = row[i]
list.append(app)
return list
#根據名稱獲取Excel表格中的數據 參數:file：Excel文件路徑 colnameindex：表頭列名所在行的所以 ，by_name：Sheet1名稱
def excel_table_byname(file= 'file.xls',colnameindex=0,by_name=u'Sheet1'):
data = open_excel(file)
table = data.sheet_by_name(by_name)
nrows = table.nrows #行數
colnames = table.row_values(colnameindex) #某一行數據
list =[]
for rownum in range(1,nrows):
row = table.row_values(rownum)
if row:
app = {}
for i in range(len(colnames)):
app[colnames[i]] = row[i]
list.append(app)
return list
def main():
tables = excel_table_byindex()
for row in tables:
print row
tables = excel_table_byname()
for row in tables:
print row
if __name__=="__main__":
main()
㈦ python如何讀取excel數據
上搜索一些教程怎麼讀寫這種專業軟體，裡面的一些數據通過它的叫聲好來讀取相關的數據。
㈧ 怎麼用python讀取excel表格的數據
一、讀excel表
讀excel要用到xlrd模塊，官網安裝（http://pypi.python.org/pypi/xlrd）。然後就可以跟著裡面的例子稍微試一下就知道怎麼用了。大概的流程是這樣的：
1、導入模塊
復制代碼代碼如下:
import xlrd
2、打開Excel文件讀取數據
復制代碼代碼如下:
data = xlrd.open_workbook('excel.xls')
3、獲取一個工作表
① table = data.sheets()[0] #通過索引順序獲取
② table = data.sheet_by_index(0) #通過索引順序獲取
③ table = data.sheet_by_name(u'Sheet1')#通過名稱獲取
4、獲取整行和整列的值（返回數組）
復制代碼代碼如下:
table.row_values(i)
table.col_values(i)
5、獲取行數和列數
復制代碼代碼如下:
table.nrows
table.ncols
6、獲取單元格
復制代碼代碼如下:
table.cell(0,0).value
table.cell(2,3).value
就我自己使用的時候覺得還是獲取cell最有用，這就相當於是給了你一個二維數組，餘下你就可以想怎麼干就怎麼幹了。得益於這個十分好用的庫代碼很是簡潔。但是還是有若干坑的存在導致話了一定時間探索。現在列出來供後人參考吧：
1、首先就是我的統計是根據姓名統計各個表中的信息的，但是調試發現不同的表中各個名字貌似不能夠匹配，開始懷疑過編碼問題，不過後來發現是因為空格。因為在excel中輸入的時候很可能會順手在一些名字後面加上幾個空格或是tab鍵，這樣看起來沒什麼差別，但是程序處理的時候這就是兩個完全不同的串了。我的解決方法是給每個獲取的字元串都加上strip（）處理一下。效果良好
2、還是字元串的匹配，在判斷某個單元格中的字元串（中文）是否等於我所給出的的時候發現無法匹配，並且各種unicode也不太奏效，網路過一些解決方案，但是都比較復雜或是沒用。最後我採用了一個比較變通的方式：直接從excel中獲取我想要的值再進行比較，效果是不錯就是通用行不太好，個呢不能問題還沒解決。
二、寫excel表
寫excel表要用到xlwt模塊，官網下載（http://pypi.python.org/pypi/xlwt）。大致使用流程如下：
1、導入模塊
復制代碼代碼如下:
import xlwt
2、創建workbook（其實就是excel，後來保存一下就行）
復制代碼代碼如下:
workbook = xlwt.Workbook(encoding = 'ascii')
3、創建表
復制代碼代碼如下:
worksheet = workbook.add_sheet('My Worksheet')
4、往單元格內寫入內容
復制代碼代碼如下:
worksheet.write(0, 0, label = 'Row 0, Column 0 Value')
5、保存
復制代碼代碼如下:
workbook.save('Excel_Workbook.xls')
由於我的需求比較簡單，所以這上面沒遇到什麼問題，唯一的就是建議還是用ascii編碼，不然可能會有一些詭異的現象。
當然xlwt功能遠遠不止這些，他甚至可以設置各種樣式之類的。附上一點例子
復制代碼代碼如下:
Examples Generating Excel Documents Using Python's xlwt
Here are some simple examples using Python's xlwt library to dynamically generate Excel documents.

style.font = font # Apply the Font to the Style
worksheet.write(0, 0, label = 'Unformatted value')
worksheet.write(1, 0, label = 'Formatted value', style) # Apply the Style to the Cell
workbook.save('Excel_Workbook.xls')
Attributes of the Font Object
font.bold = True # May be: True, False
font.italic = True # May be: True, False

㈨ python怎麼讀取excel的數據
最近由於經常要用到Excel，需要根據Excel表格中的內容對一些apk進行處理，手動處理很麻煩，於是決定寫腳本來處理。首先貼出網上找來的讀寫Excel的腳本。
1.讀取Excel(需要安裝xlrd)：
2.寫入Excel（需安裝pyExcelerator）
3.再舉個自己寫的讀寫Excel的例子
讀取reflect.xls中的某些信息進行處理後寫入mini.xls文件中。
4.現在我需要根據Excel文件中滿足特定要求的apk的md5值來從伺服器獲取相應的apk樣本，就需要這樣做：
補充一個使用xlwt3進行Excel文件的寫操作。
2526import xlwt3if __name__ == '__main__':datas = [['a', 'b', 'c'], ['d', 'e', 'f'], ['g', 'h']]#二維數組file_path = 'D:\test.xlsx'wb = xlwt3.Workbook()sheet = wb.add_sheet('test')#sheet的名稱為test#單元格的格式style = 'pattern: pattern solid, fore_colour yellow; '#背景顏色為黃色style += 'font: bold on; '#粗體字style += 'align: horz centre, vert center; '#居中header_style = xlwt3.easyxf(style)row_count = len(datas)col_count = len(datas[0])for row in range(0, row_count):col_count = len(datas[row])for col in range(0, col_count):if row == 0:#設置表頭單元格的格式sheet.write(row, col, datas[row][col], header_style)else:sheet.write(row, col, datas[row][col])wb.save(file_path)輸出的文件內容如下圖：
註：以上代碼在Python 3.x版本測試通過。
好了，python操作Excel就這么！些了，簡單吧
