我有一个PDF表单，需要多次填写（确切地说是时间表）。现在因为我不想手动执行此操作，我正在寻找一种方法来使用python脚本或可以在bash脚本中使用的工具来填充它们。
有没有人有这方面的经验？

对于Python，你需要fdfgen lib和pdftk
@Hugh Bothwell的评论是100％正确的，所以我会用一个有效的实现来扩展答案。
如果你在Windows中，你还需要确保系统路径中包含python和pdftk（除非你想使用长文件夹名称）。
以下是从CSV数据文件中自动批量填充PDF表单集合的代码：
import csv
from fdfgen import forge_fdf
import os
import sys
sys.path.insert(0, os.getcwd())
filename_prefix = "NVC"
csv_file = "NVC.csv"
pdf_file = "NVC.pdf"
tmp_file = "tmp.fdf"
output_folder = './output/'
def process_csv(file):
headers = []
data = []
csv_data = csv.reader(open(file))
for i, row in enumerate(csv_data):
if i == 0:
headers = row
continue;
field = []
for i in range(len(headers)):
field.append((headers[i], row[i]))
data.append(field)
return data
def form_fill(fields):
fdf = forge_fdf("",fields,[],[],[])
fdf_file = open(tmp_file,"w")
fdf_file.write(fdf)
fdf_file.close()
output_file = '{0}{1} {2}.pdf'.format(output_folder, filename_prefix, fields[1][1])
cmd = 'pdftk "{0}" fill_form "{1}" output "{2}" dont_ask'.format(pdf_file, tmp_file, output_file)
os.system(cmd)
os.remove(tmp_file)
data = process_csv(csv_file)
print('Generating Forms:')
print('-----------------------')
for i in data:
if i[0][1] == 'Yes':
continue
print('{0} {1} created...'.format(filename_prefix, i[1][1]))
form_fill(i)
注意：要弄清楚如何定制它，不应该是火箭手术。初始变量声明包含自定义配置。
在CSV中，在第一行中，每列将包含PDF文件中相应字段名称的名称。任何在模板中没有相应字段的列都将被忽略。
在PDF模板中，只需创建您希望填充数据的可编辑字段，并确保名称与CSV数据匹配。
对于此特定配置，只需将此文件放在与NVC.csv，NVC.pdf和名为“output”的文件夹相同的文件夹中。运行它并自动完成剩下的工作。

更快的版本，不需要pdftk和fdfgen，纯Python 3.6 +：
# -*- coding: utf-8 -*-
from collections import OrderedDict
from PyPDF2 import PdfFileWriter, PdfFileReader
def _getFields(obj, tree=None, retval=None, fileobj=None):
"""
Extracts field data if this PDF contains interactive form fields.
The *tree* and *retval* parameters are for recursive use.
:param fileobj: A file object (usually a text file) to write
a report to on all interactive form fields found.
:return: A dictionary where each key is a field name, and each
value is a :class:`Field<PyPDF2.generic.Field>` object. By
default, the mapping name is used for keys.
:rtype: dict, or ``None`` if form data could not be located.

替换原始文件
os.system('pdftk "original.pdf" fill_form "data.fdf" output "output.pdf"')
os.remove("data.fdf")
os.remove("original.pdf")
os.rename("output.pdf","original.pdf")

我编写了一个基于以下内容构建的库：'pdfrw'、'pdf2image'、'Pillow'、'PyPDF2'，称为 fillpdf（pip install fillpdf 和 poppler 依赖项 conda install -c conda-forge poppler）
基本用法：
from fillpdf import fillpdfs
fillpdfs.get_form_fields("blank.pdf")
# returns a dictionary of fields
# Set the returned dictionary values a save to a variable
# For radio boxes ('Off' = not filled, 'Yes' = filled)
data_dict = {
'Text2': 'Name',
'Text4': 'LastName',
'box': 'Yes',
}
fillpdfs.write_fillable_pdf('blank.pdf', 'new.pdf', data_dict)
# If you want it flattened:
fillpdfs.flatten_pdf('new.pdf', 'newflat.pdf')

如果某些字段没有填写，可以使用 fitz (pip install PyMuPDF) 和 PyPDF2 (pip install PyPDF2) 如下所示根据需要更改点：
import fitz
from PyPDF2 import PdfFileReader
file_handle = fitz.open('blank.pdf')
pdf = PdfFileReader(open('blank.pdf','rb'))
box = pdf.getPage(0).mediaBox
w = box.getWidth()
h = box.getHeight()
# For images
image_rectangle = fitz.Rect((w/2)-200,h-255,(w/2)-100,h-118)
pages = pdf.getNumPages() - 1
last_page = file_handle[pages]
last_page._wrapContents()
last_page.insertImage(image_rectangle, filename=f'image.png')
# For text
last_page.insertText(fitz.Point((w/2)-247 , h-478), 'John Smith', fontsize=14, fontname="times-bold")
file_handle.save(f'newpdf.pdf')
