設想大多數說明建議您可以使用 python 生成 PlantUML 圖python -m plantuml example_diagram.txt：我想創建一個 python 腳本，它在創建時生成多個 PlantUML 圖，這樣我就可以立即更新一組完整的圖，而無需運行多個命令。示例文件以下文件用于生成 PlantUML 圖：example_flow.txt內容：' http://tonyballantyne.com/graphs.html#orgheadline19' http://graphviz.org/doc/info/shapes.html' Indicate the direction of the flowchartleft to right direction' Give a block the variable name 'first' and define starting point as (*)(*) --> "The first block" as firstfirst --> "A" as A' Give the block a variable name s.t. you can just use its variable name in the next blocks --> "D" as Dfirst --> "B" as B --> Dfirst --> "C" as C --> D ' Define end point as (*) D --> (*)Graphviz_example.txt內容：' http://tonyballantyne.com/graphs.html#orgheadline19' http://graphviz.org/doc/info/shapes.htmldigraph summary{ // initialize the variable blocks start [label="Start with a Node"] next [label="Choose your shape", shape=box] warning [label="Don't go overboard", color=Blue, fontcolor=Red,fontsize=24,style=filled, fillcolor=green,shape=octagon] end [label="Draw your graph!", shape=box, style=filled, fillcolor=yellow] // Indicate the direction of the flowchart rankdir=LR; // Rank direction left to right // Create the connections start->next start->warning next->end [label="Getting Better...", fontcolor=darkblue]}問題如何從單個 python 腳本創建這些圖表？

為同一目錄下的2個文件生成
創建一個以內容命名的 python 文件create_diagrams.py：
from plantuml import PlantUML
from os.path import abspath
# create a server object to call for your computations
server = PlantUML(url='http://www.plantuml.com/plantuml/img/',
basic_auth={},
form_auth={}, http_opts={}, request_opts={})
# Send and compile your diagram files to/with the PlantUML server
server.processes_file(abspath('./example_flow.txt'))
server.processes_file(abspath('./Graphviz_example.txt'))
并運行它，例如在帶有 python 3.6 的 anaconda 中使用命令：python create_diagrams.py。
為目錄中的所有文件生成
還可以為.txt目錄中的所有文件生成圖表Diagrams：
from plantuml import PlantUML
import os
from os.path import abspath
server = PlantUML(url='http://www.plantuml.com/plantuml/img/',
basic_auth={},
form_auth={}, http_opts={}, request_opts={})
# create subfolder name
diagram_dir = "./Diagrams"
# loop through all .txt files in the subfolder
for file in os.listdir(diagram_dir):
filename = os.fsdecode(file)
if filename.endswith(".txt"):
# Call the PlantUML server on the .txt file
server.processes_file(abspath(f'./Diagrams/{filename}'))
筆記
此實現需要有效的互聯網連接，因為您要求 PlantUML 服務器為您生成圖形。要在本地編譯，您還可以下載.jarPlantUML 軟件的文件并從 python 調用它來進行計算。這篇文章的問題中給出了一個更詳細的例子。
