I have the this:
name = ['Anca', 'Bogdan', 'Francois', 'Jerome', 'Simina'];
for i=1:size(name,1)
temp = name(i,:);
tempwav = wavread(temp);
end
And I get this error:
Error in Load_data (line 7)
tempwav = wavread(temp);
meaning this line: tempwav = wavread(temp);
The .wav files are there I just don't know what is the problem. Pls help
Your way of creating the variable name will result in the value AncaBogdanFrancoisJeromeSimina. Instead you should use a cell array (note the curly brackets)
name = {'Anca', 'Bogdan', 'Francois', 'Jerome', 'Simina'};
for i=1:length(name)
temp = name{i};
tempwav = wavread(temp);
end

I am unable to parse a JSON array from a text file due to errors and my limited knowledge of JSON.
The file looks something like this [{"random":"fdjsf","random56":128,"name":"dsfjsd", "rid":1243,"rand":674,"name":"dsfjsd","random43":722, "rid":126},{"random":"fdfgfgjsf","random506":120,"name":"dsfjcvcsd", "rid":12403,"rando":670,"name":"dsfooojsd","random4003":720, "rid":120}] It has more than one object({}) in the entire array however I did not want to include all 600. The layout shown above is basically how all of them look.
r = s.get(getAPI, headers=header, verify=False)
f = open('text.txt', 'w+')
f.write(r.text)
f.close
output_file = open ('text.txt', 'r')
json_array = json.load(output_file)
json_list = []
for item in json_array:
name = "name"
rid = "rid"
json_items = {name:None, rid:None}
json_items = [name] = item[name]
json_items = [rid] = item[rid]
json_list.append(json_items)
print(json_list)
I would like to loop through an array and find any time it says "name":... eventually followed by "rid":... and store those in a dictionary as key value pairs.
Errors:
ValueError: too many values to unpack (expected 1)
There is a syntax error when you assign values to json_items, change it to:
json_items[name] = item[name]
json_items[rid] = item[rid]
I have two sets of arrays stored in a file and I need to extract values one by one and compare them. I am using this code but does look like I am doing correctly.
# First Dataset
File.foreach(file_set_a) do |data_a|
data_array_a = data_a.split("\t")
#file_name_a = data_array_a[0]
#file_ext_a = data_array_a[1]
# Second Dataset
File.foreach(file_set_b) do |data_b|
data_array_b = data_b.split("\t")
#file_name_b = data_array_b[0]
#file_ext_b = data_array_b[1]
#Compare
#file_name_a == #file_name_b
end
end
The problem is, I cannot go back and extract the next values in the set A when I enter the set B. Any suggestions?
First, convert those 2 files into two separated data arrays
lines_array_a = File.readlines(file_set_a)
lines_array_b = File.readlines(file_set_b)
I am assuming both of the array size will be same. Now run a loop and get the items from both array to compare them.
for i in 0..(lines_array_a.count - 1) do
data_array_a = lines_array_a[i].split("\t")
#file_name_a = data_array_a[0]
#file_ext_a = data_array_a[1]
data_array_b = lines_array_b[i].split("\t")
#file_name_b = data_array_b[0]
#file_ext_b = data_array_b[1]
#file_name_a == #file_name_b
end

Issue querying from Access database: "could not convert string to float: E+6"
(3 answers)
Closed 7 years ago.
I am trying to access some of the columns in a Microsoft Access database table which contains numbers of type double but I am getting the error mentioned in the title.The code used for querying the database is as below, the error is occurring in the line where cur.execute(....) command is executed. Basically I am trying filter out data captured in a particular time interval. If I exclude the columns CM3_Up, CG3_Up, CM3_Down, CG3_Down which contains double data type in the cur.execute(....) command I wont get the error. Same logic was used to access double data type from other tables and it worked fine, I am not sure what is going wrong.
Code:
start =datetime.datetime(2015,03,28,00,00)
a=start
b=start+datetime.timedelta(0,240)
r=7
while a < (start+datetime.timedelta(1)):
params = (a,b)
sql = "SELECT Date_Time, CM3_Up, CG3_Up, CM3_Down, CG3_Down FROM
Lysimeter_Facility_Data_5 WHERE Date_Time >= ? AND Date_Time <= ?"
for row in cur.execute(sql,params):
if row is None:
continue
r = r+1
ws.cell(row = r,column=12).value = row.get('CM3_Up')
ws.cell(row = r,column=13).value = row.get('CG3_Up')
ws.cell(row = r,column=14).value = row.get('CM3_Down')
ws.cell(row = r,column=15).value = row.get('CG3_Down')
a = a+five_min
b = b+five_min
wb.save('..\SE_SW_Lysimeters_Weather_Mass_Experiment-02_03_26_2015.xlsx')

ValueError: could not convert string to float: E-3
As to this discussion:
Python: trouble reading number format
the trouble could be that e should be d, like:
float(row.get('CM3_Up').replace('E', 'D'))
Sounds weird to me though, but I know only little of Python.
It sounds like you receive strings like '2.34E-3', so try with a conversion. Don't know Python, but in C# it could be like:
ws.cell(row = r,column=12).value = Convert.ToDouble(row.get('CM3_Up'))
ws.cell(row = r,column=13).value = Convert.ToDouble(row.get('CG3_Up'))
ws.cell(row = r,column=14).value = Convert.ToDouble(row.get('CM3_Down'))
ws.cell(row = r,column=15).value = Convert.ToDouble(row.get('CG3_Down'))
I'm having a few problems with the following:
Dim design(6) As String
design(0) = "DES1"
design(1) = "DES1_slot"
design(2) = "DES2"
design(3) = "DES2_slot"
design(4) = "DES3"
design(5) = "DES3_slot"
I get the error "Expected end of statement"
Similarly:
Dim design(0 To 5) As String
design(0) = "DES1"
design(1) = "DES1_slot"
design(2) = "DES2"
design(3) = "DES2_slot"
design(4) = "DES3"
design(5) = "DES3_slot"
says "Expecting ')' "
I don't often use VBA, but from the quick googling I did at least one of these should work?
Thats perfectly valid VBA however you will get those exact errors in VBScript which is what I presume your using.
As VBScript is typeless change the first line to just:
Dim design(5)
The code I'm using imports data from multiple files and saves them into an array of cells, the code is as follows:
[FileName,PathName,FilterIndex] = uigetfile('*.txt*','MultiSelect','on');
numfiles = size(FileName,2);
FileData= cell(1,numfiles);
for ii = 1:numfiles
FileName{ii};
A=[];
entirefile =fullfile(PathName,FileName{ii});
fid = fopen(entirefile);
tline = fgets(fid);
while ischar(tline)
parts = textscan(tline, '%f;');
if numel(parts{1}) > 0
A = [ A ; parts{:}' ];
end
tline = fgets(fid);
end
fclose(fid);
FileData{ii} = A;
A = FileData{ii};
X = A(:,1);
Y = A(:,5);
DataToUse = [X,Y];
end
Now my issue is I want to use the first DataToUse created by the loop, which will be data from the first file, seperatley to the other files but I can not issolate it. I have tried DataToUse(1), DataToUse(1,1) and DataToUse(:,[1,2]) but none are working for me. An example of the type of data would be:
DataToUse=
0.0762 0.0271
0.0763 0.2671
0.0764 0.4079
0.0765 0.0510
0.0766 0.0087
0.0767 0.0099
0.0768 0.0067
0.0769 0.0047
0.0770 0.0047
0.0771 0.0349
0.0772 0.2094
0.0773 0.2740
0.0774 0.0294
0.0775 0.0100
0.0776 0.0159
I have different numbers of this kind of data depending on how many files are selected but I would like to only use the first initially and use the others later. Anybody know how I can go about doing this? Many thanks in advance
The solution is to use cell arrays, like so:
DataToUse{ii} = [X, Y]
To get the desired output put this after your for-loop:
firstLoopXY = DataToUse{1}
Enjoy!
