I tried soe code:
but not getting expected result.
prob = LpProblem("choose project")
project_list = list(df['project'])
banglore = dict(zip(project_list,df['loc_Bangalore']))
pune = dict(zip(project_list,df['loc_Pune']))
c = dict(zip(project_list,df['cat_C']))
s = dict(zip(project_list,df['cat_S']))
proj_vars = pulp.LpVariable.dicts("project",project_list,cat='Binary')
no_of_project_choose = 5
prob += pulp.lpSum([banglore[f] * proj_vars[f] for f in project_list]) <= 3
prob += pulp.lpSum([pune[f] * proj_vars[f] for f in project_list]) <=2
prob += pulp.lpSum([c[f] * proj_vars[f] for f in project_list]) <=4
prob += pulp.lpSum([s[f] * proj_vars[f] for f in project_list]) <=1
prob += pulp.lpSum([[banglore[f] * proj_vars[f] for f in project_list]+[pune[f] * proj_vars[f] for f in project_list]+
[c[f] * proj_vars[f] for f in project_list]+[s[f] * proj_vars[f] for f in project_list]]) <=5
prob.solve()
> output: abc 0.0, sys 0.0, syst None, EPS 0.0 , foss 0.0 , opc
> None(i am getting all project with 0 or some number line abc 9)
Pls help me in solving this.I want only project which satisfy other condition also(like banglore, pune,c and s).
is there anyother way of solving this?
i m not sue about my solution and way of solving.plz help.

Hi @pallavi@76,
I have no clue what your are talking about but I am pretty sure this is the wrong forum for your question. This forum is related to PULP, the parallel ultra low power platform, which is a project that aims to develop open source low power processor architectures and digital IPs in general. Your question seems to be related to some python project.
Best,
Manuel
