在多个文件中追加多行

问题描述

我需要创建一定数量的文件，这些文件总是在他们里面同样的思路。

使用此脚本，我可以创建“schede”文件夹，其中创建了一定数量的 *.tex 文件。

乳胶串被写入仅在最后一个标签，而其他保持空白。我如何填写所有表格？

import os
import subprocess
work_path = os.path.abspath(os.path.dirname(__file__))
if not os.path.exists("schede"):
    os.mkdir("schede")
os.chdir(os.path.expanduser(work_path+"/schede"))
n = 5   #put the number as you wish

for i in range(n):
    file_name = "S"+str(i).zfill(1)+".tex"
    subprocess.call(['touch',file_name]) #crea 34 file s.tex

def append_new_line(file_name,text_to_append):
    """Append given text as a new line at the end of file"""
    # Open the file in append & read mode ('a+')
    with open(file_name,"a+") as file_object:
        # Move read cursor to the start of file.
        file_object.seek(0)
        # If file is not empty then append '\n'
        data = file_object.read(100)
        if len(data) > 0:
            file_object.write("\n")
        # Append text at the end of file
        file_object.write(text_to_append)
        
def append_multiple_lines(file_name,lines_to_append):
    # Open the file in append & read mode ('a+')
    with open(file_name,"a+") as file_object:
        appendEOL = False
        # Move read cursor to the start of file.
        file_object.seek(0)
        # Check if file is not empty
        data = file_object.read(100)
        if len(data) > 0:
            appendEOL = True
        # Iterate over each string in the list
        for line in lines_to_append:
            # If file is not empty then append '\n' before first line for
            # other lines always append '\n' before appending line
            if appendEOL == True:
                file_object.write("\n")
            else:
                appendEOL = True
            # Append element at the end of file
            file_object.write(line)

def main():
    append_new_line(file_name,'This is second line')
    print('Append multiple lines to a file in Python')
    list_of_lines = [
        '\ecvtitle{}{}','\ecvitem{\ecvhighlight{Organizzato da:}}{\\textbf{}}','\ecvitem{\ecvhighlight{}}{}','\ecvitem{}{}','\ecvitem{\ecvhighlight{Programma Formativo:}}{}','\smallskip','\ecvitem{}{','\\begin{ecvitemize}'
            '\item  scrivere un\'item','\\end{ecvitemize}','}']
    # Append strings in list as seperate new lines in the end of file
    append_multiple_lines(file_name,list_of_lines)

if __name__ == '__main__':
   main()

解决方法

正如 @MisterMiyagi 所说的 file_name 是一个变量，所以每次创建文件时它都会被覆盖

我建议创建一个名为 files = [] 的列表 而不仅仅是file_name = "S"+str(i).zfill(1)+".tex"

添加files.append(file_name) 到您创建文件的 for 循环的末尾。

并更改 main 以执行每个文件的说明。

def main():
    for file_name in file:
        append_new_line(file_name,'This is second line')
        print('Append multiple lines to a file in Python')
        list_of_lines = [
        '\ecvtitle{}{}','\ecvitem{\ecvhighlight{Organizzato da:}}{\\textbf{}}','\ecvitem{\ecvhighlight{}}{}','\ecvitem{}{}','\ecvitem{\ecvhighlight{Programma Formativo:}}{}','\smallskip','\ecvitem{}{','\\begin{ecvitemize}'
        '\item  scrivere un\'item','\\end{ecvitemize}','}']
        # Append strings in list as seperate new lines in the end of file
        append_multiple_lines(file_name,list_of_lines)
