使用Python读取 excel 文件

使用 xlrd 模块，可以从电子表格中检索信息。例如，可以在Python中读取、写入或修改数据。此外，用户可能必须浏览各种工作表并根据某些标准检索数据或修改某些行和列并做很多工作。

xlrd模块用于从电子表格中提取数据。

注意： xlrd 已明确删除对读取 xlsx 表的支持。安装 xlrd 模块的命令：

pip install xlrd

输入文件：

代码 #1：提取特定单元格

Python3

# Reading an excel file using Python
import xlrd
 
# Give the location of the file
loc = ("path of file")
 
# To open Workbook
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
 
# For row 0 and column 0
print(sheet.cell_value(0, 0))

输出 ：

'NAME'

代码#2：提取行数

Python3

# Program to extract number
# of rows using Python
import xlrd
 
# Give the location of the file
loc = ("path of file")
 
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
sheet.cell_value(0, 0)
 
# Extracting number of rows
print(sheet.nrows)

输出 ：

4

代码#3：提取列数

Python3

# Program to extract number of
# columns in Python
import xlrd
 
loc = ("path of file")
 
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
 
# For row 0 and column 0
sheet.cell_value(0, 0)
 
# Extracting number of columns
print(sheet.ncols)

输出 ：

3

代码#4：提取所有列名

Python3

# Program extracting all columns
# name in Python
import xlrd
 
loc = ("path of file")
 
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
 
# For row 0 and column 0
sheet.cell_value(0, 0)
 
for i in range(sheet.ncols):
    print(sheet.cell_value(0, i))

输出 ：

NAME
SEMESTER
ROLL NO

代码 #5：提取第一列

Python3

# Program extracting first column
import xlrd
 
loc = ("path of file")
 
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
sheet.cell_value(0, 0)
 
for i in range(sheet.nrows):
    print(sheet.cell_value(i, 0))

输出 ：

NAME
ALEX
CLAY
JUSTIN

代码 #6：提取特定的行值

Python3

# Program to extract a particular row value
import xlrd
 
loc = ("path of file")
 
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
 
sheet.cell_value(0, 0)
 
print(sheet.row_values(1))

输出 ：

['ALEX', 4.0, 2011272.0]
