The purpose of his application is to automatically generate pert chart from tasks in json file.
pip install pertchart
from pertchart import PertChart
pc = PertChart()
tasks = pc.getInput(path_to_inputfile)
pc.create_pert_chart(pc.calculate_values(tasks))
The data file contains task tuples one per line as in the following sample:
{
"T1.1": {
"Tid": "T1.1",
"start": 0,
"duration": 1,
"end": 0,
"responsible": "Responsible1",
"pred": ["START"]
},
"T1.2": {
"Tid": "T1.2",
"start": 0,
"duration": 3,
"end": 0,
"responsible": "Responsible2",
"pred": ["T1.1"]
},
"T1.3": {
"Tid": "T1.3",
"start": 0,
"duration": 3,
"end": 0,
"responsible": "Responsible3",
"pred": ["T1.1"]
},
"T1.4": {
"Tid": "T1.4",
"start": 0,
"duration": 2,
"end": 0,
"responsible": "Responsible4",
"pred": ["T1.2"]
},
"T1.5": {
"Tid": "T1.5",
"start": 0,
"duration": 2,
"end": 0,
"responsible": "Responsible5",
"pred": ["T1.3"]
},
"T1.6": {
"Tid": "T1.6",
"start": 0,
"duration": 1,
"end": 0,
"responsible": "Responsible6",
"pred": ["T1.4"]
},
"T1.7": {
"Tid": "T1.7",
"start": 0,
"duration": 3,
"end": 0,
"responsible": "Responsible7",
"pred": ["START"]
},
"T1.8": {
"Tid": "T1.8",
"start": 0,
"duration": 0,
"end": 0,
"responsible": "Responsible8",
"pred": ["T1.5","T1.6","T1.7"]
},
"END": {
"Tid": "END",
"start": 0,
"duration": 0,
"end": 0,
"responsible": "Responsible",
"pred": ["T1.8"]
}
