Python - 写矩阵到txt文件,保持格式 [英] Python - Write matrix to txt file, keep formatting
问题描述
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $# ('MY_DIRECTORY'):#替换为实际的目录路径
用于文件名的文件名(文件名','日期']
矩阵= [titles]
用于目录,__,os.walk :
with open(os.path.join(directory,filename))as f:
name,date = f.readline()。strip().split()
print(name )
row = [name,date.split('。')[ - 1]]
for line in f:
header,value = line.strip()。split(' ')
if len(matrix)== 1:
titles.append(header)
row.append(value)
matrix.append(row)
#计算列的宽度
column_widths = [0] * len(标题)
为矩阵中的行:
为列,枚举中的数据(行):
column_widths [column] = max(column_widths [column],len(data))
formats = ['{:%s%ss}' %('^'if c> 1 else'<',w)for c,w in enumerate(column_widths)]
用于矩阵中的行:
for column ,枚举(行)中的数据:
print(formats [column] .format(data)),
这个输出如下所示,在第一行中有一个单词选择,在每一个我正在处理的文件中都有一个明显的条目:
文件名Date('in','usd','millions')('indd','zurich','financial')('table','in '''''''''''''''''''''''''''''''''''''''''''''''''''''$'

现在我试图把这个写到一个txt文件中,但我没有弄明白,有什么建议吗?如果你只是试图写出你当前正在打印的文件,那么它就不是这么简单:
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ :
out + = formats [column] .format(data)
out + =\\\
with open(out.txt,wt) as file:
file.write(out)
I am struggeling in writing the output of my code to a txt file while keeping the format. Here is the code:
import os
# Compute matrix
titles = ['Filename', 'Date']
matrix = [titles]
for directory, __, files in os.walk('MY_DIRECTORY'): # replace with actual directory path
for filename in files:
with open(os.path.join(directory, filename)) as f:
name, date = f.readline().strip().split()
print(name)
row = [name, date.split('.')[-1]]
for line in f:
header, value = line.strip().split(':')
if len(matrix) == 1:
titles.append(header)
row.append(value)
matrix.append(row)
# Work out column widths
column_widths = [0]*len(titles)
for row in matrix:
for column, data in enumerate(row):
column_widths[column] = max(column_widths[column], len(data))
formats = ['{:%s%ss}' % ('^' if c>1 else '<', w) for c, w in enumerate(column_widths)]
for row in matrix:
for column, data in enumerate(row):
print(formats[column].format(data)),
print
The output of this looks like the following, where I have a selection of words in the first row and a line wise entry for each file I am processing:
Filename Date ('in', 'usd', 'millions') ('indd', 'zurich', 'financial') ('table', 'in', 'usd') ('group', 'executive', 'committee') ('years', 'ended', 'december')

COMPANYA 2012 1 2 3 4 5
Now I tried to write this to an txt file, but I didnt figure it out, any suggestions?
If you're really only trying to write the string you're currently printing to a file, then it's not much more than this:
out = ""
for row in matrix:
for column, data in enumerate(row):
out += formats[column].format(data)
out += "\n"
with open("out.txt","wt") as file:
file.write(out)
