Python - 以CSV格式从Excel电子表格打印单个单元格

Question

I have an excel spreadsheet saved as a CSV file, but cannot find a way to call individual values from cells into Python using the CSV module. Any help would be greatly appreciated

Answer 1

There is also a Python library capable of reading xls data. Have a look at python-xlrd .

For writing xls data, you can use python-xlwt .

Answer 2

The csv module provide readers that iterate over the rows of a csv file - the rows are lists of strings. One way to get access to individual cells would be to:

Read the entire file in as a list of lists

import csv
with open('test.csv', 'r') as f:
    reader = csv.reader(f)
    the_whole_file = list(reader)

Then access the individual cells by indexing into the_whole_file . The first index is the row and the second index is the column - both are zero based. To access the cell at the second row, fourth column:

row = 1
column = 3
cell_R1_C3 = the_whole_file[row][column]

print cell_R1_C3

Answer 3

If you have the excel file as a CSV, you can use csv.reader

import csv
myFilePath = "/Path/To/Your/File"
with open(myFilePath,'rb') as csvfile:
    reader = csv.reader( csvfile, delimiter=',' )
    for row in reader:
        # 'row' has all the cells (thanks to wwii for the fix!). Get the first 4 columns
        a, b, c, d = row[:4]
