到目前为止,我的代码从文本文件中读取并导出到Excel,我有:
import glob
data = {}
for infile in glob.glob("*.txt"):
with open(infile) as inf:
data[infile] = [l[:-1] for l in inf]
with open("summary.xls", "w") as outf:
outf.write("\t".join(data.keys()) + "\n")
for sublst in zip(*data.values()):
outf.write("\t".join(sublst) + "\n")
此目标是访问特定文件夹中的所有文本文件。
但是,当我运行它时,Excel会给我一个错误说,
"无法打开文件,原因是:文档顶层无效。第1行,位置1. outputgooderr.txt outputbaderr.txt。 fixed_inv.txt
注意:outputgooderr.txt,outputbaderr.txt。,fixed_inv.txt是我要导出到Excel的文本文件的名称,每张一个文件。
当我只有一个文件供程序读取时,它能够提取数据。不幸的是,由于我有多个文件,这不是我想要的。
请让我知道我可以解决这个问题的任何方法。我非常喜欢编程的初学者,并且非常感谢任何建议!谢谢。

如果你不反对将输出的excel文件作为.xlsx而不是.xls,我建议使用Pandas的一些功能。特别是pandas.read_csv()和DataFrame.to_excel()
我提供了一个完全可重复的示例,说明如何执行此操作。请注意,我在测试的前3行中创建了2个.txt文件。
import pandas as pd
import numpy as np
import glob
# Creating a dataframe and saving as test_1.txt/test_2.txt in current directory
# feel free to remove the next 3 lines if yo want to test in your directory
df = pd.DataFrame(np.random.randn(10, 3), columns=list('ABC'))
df.to_csv('test_1.txt', index=False)
df.to_csv('test_2.txt', index=False)
txt_list = [] # empty list
sheet_list = [] # empty list
# a for loop through filenames matching a specified pattern (.txt) in the current directory
for infile in glob.glob("*.txt"):
outfile = infile.replace('.txt', '') #removing '.txt' for excel sheet names
sheet_list.append(outfile) #appending for excel sheet name to sheet_list
txt_list.append(infile) #appending for '...txt' to txtt_list
writer = pd.ExcelWriter('summary.xlsx', engine='xlsxwriter')
# a for loop through all elements in txt_list
for i in range(0, len(txt_list)):
df = pd.read_csv('%s' % (txt_list[i])) #reading element from txt_list at index = i
df.to_excel(writer, sheet_name='%s' % (sheet_list[i]), index=False) #reading element from sheet_list at index = i
writer.save()
输出示例:
