join - How can work output on python? -


i want made script storage capacity modify have problem.

my script has below error:

traceback (most recent call last):   file "test.py", line 20, in <module>     mod_f.write(','.join(line) + '\n') typeerror: sequence item 3: expected string, float found

below script.

mod_f = open("mod_c_vol_size.txt", 'w') mod_f.write("vserver,volume,aggregate,total,avail,node,savea,saved,savec,snap,tused\n") unit = ['tb', 'gb', 'mb', 'kb', 'b'] open("find_c_vol_modify.txt", "r") f:         next(f)         line in f:                 if len(line.strip()) != 0:                         line = line.split(',')                         out = []                         l in line[3:5] + line[6:11]:                                 l = l.replace('\n','')                                 try:                                         ind = [unit[i] in l in range(5)].index(true)                                 except valueerror:                                         print('please check script')                                  val = str(l.split(unit[ind])[0])                                 out.append(float(val)/1024**ind)                         line = line[0:3] + out[:-5] + line[5:6] + out[2:]                         print (line) mod_f.write(','.join(line) + '\n') mod_f.close()

error @ line mod_f.write(','.join(line) + '\n')

below input text file.

vserver,volume,aggregate,total,avail,node,savea,saved,savec,snap,tused xxxx,yyyy,node1_aggr1,1tb,1023gb,fas8040-zzzz,0b,0b,0b,0b,177.7mb xxxx,zzzz,node1_aggr1,3tb,3.00tb,fas8040-zzzz,0b,0b,0b,0b,1.60gb xxxx,cccc,node1_aggr1,1tb,907.9gb,fas8040-zzzz,0b,0b,0b,0b,116.1gb xxxx,vvvv,node1_aggr1,200gb,200.0gb,fas8040-zzzz,0b,0b,0b,0b,6.25mb

below expected output file.

['xxxx', 'yyyy', 'node1_aggr1', 1.0, 0.9990234375, 'fas8040-zzzz', 0.0, 0.0, 0.0, 0.0, 0.00016946792602539061] ['xxxx', 'zzzz', 'node1_aggr1', 3.0, 3.0, 'fas8040-zzzz', 0.0, 0.0, 0.0, 0.0, 0.0015625] ['xxxx', 'cccc', 'node1_aggr1', 1.0, 0.88662109375, 'fas8040-zzzz', 0.0, 0.0, 0.0, 0.0, 0.11337890625] ['xxxx', 'vvvv', 'node1_aggr1', 0.1953125, 0.1953125, 'fas8040-zzzz', 0.0, 0.0, 0.0, 0.0, 5.9604644775390625e-06]

the fourth item in each line list float element computed: 1.0, 3.0, 1.0, 0.1953125 (as later elements). join works on strings. you'll need convert float items string somewhere. perhaps

out.append(str(float(val)/1024**ind))

or generality before write

line = [str(item) item in line]

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
