[英]How to search and replace string in excel (.xls) file using Python?
i am trying to use search and replace string in excel file (xls), actually - i need to find string and add before prefix *.我正在尝试在 excel 文件(xls)中使用搜索和替换字符串,实际上 - 我需要在前缀 * 之前找到字符串并添加。 For example
例如
But i am getting a error:但我收到一个错误:
LVdemact = {'two': two_replaced, 'six': six_replaced, 'five': five_replaced}
NameError: name 'two_replaced' is not defined
Code:代码:
from xlrd import open_workbook
from xlutils.copy import copy
import xlsxwriter
rb = open_workbook("template.xlsx")
# Create an new Excel file and add a worksheet.
wb = xlsxwriter.Workbook('Updated_Workbook1.xlsx')
ws = wb.add_worksheet()
s_orig = rb.sheet_by_index(0)
LVdemact = {'two': two_replaced, 'six': six_replaced, 'five': five_replaced,}
for row in range(s_orig.nrows):
for col in range(s_orig.ncols):
if s_orig.cell(row,col).value in LVdemact:
# s.write(row, col, LVdemact[item])
ws.write(row, col, LVdemact[s_orig.cell(row,col).value])
else:
ws.write(row, col, s_orig.cell(row,col).value)
wb.close()
The issue is in the line - LVdemact = {'two': two_replaced, 'six': six_replaced, 'five': five_replaced,}
问题出在一行 -
LVdemact = {'two': two_replaced, 'six': six_replaced, 'five': five_replaced,}
variables two_replaced
, six_replaced
and five_replaced
are not defined.变量
two_replaced
、 six_replaced
和five_replaced
未定义。 Do you want this to be a string?你希望这是一个字符串吗? then define this in this way -
然后以这种方式定义它 -
LVdemact = {'two': 'two_replaced', 'six': 'six_replaced', 'five': 'five_replaced'}
You can use this你可以用这个
df = pd.DataFrame() # Your dataframe
for column in df.select_dtypes('object'):
df[column] = df[column].str.replace('toreplace','newword')
