I get the following error and don't know how to resolve it:
if marks >= 70:
TypeError: '>=' not supported between instances of 'list' and 'int'
MY CODE:
import csv, array
filename = 'students.csv'
name = []
marks = []
grade = []
v = ""
with open(filename) as f:
reader = csv.reader(f)
for row in reader:
name.append(row[0])
marks.append(row[1])
if marks >= 70:
v = "A"
grade.append(v)
elif marks >= 60:
v = "B"
grade.append(v)
elif marks >= 50:
v = "C"
grade.append(v)
else:
v = "D"
grade.append(v)
print(name)
print(marks)
print(grade)
I have tried setting marks to:
marks = [0] * 20, along with setting the other arrays to store 20 values.

Hello i have an assignment that I can find out. The questions for the assignment is:
Make a loop that tries to decrypt the ciphertext with all possible keys one at a time.
For each loop, each individual word is looked up in the dictionary. If 85% of the words are found in the dictionary, then it is probably the right key in the current run, and then the loop must be broken.
Decrypt the text with the found key and print it.
I have a code that takes all words from a dictionary and count them. I have linked the dsv file. Hope you can help me.

I have tried to make a loop. But it didn't work
I have a list of xy points that I'm trying to sum together and identify the centroid, but it only uses the last value in the row. I'm trying to create a centroid for each state, Here's the code:
Total_X1 = 0
Total_Y1 = 0
TotalPop1 = 0
#Cat = "cali"
cntyName1 = "cnty"
stateName1 = "statename"
for row in cursor:
#if row[0] >= : ### for condition that is met
#if row[0]== []:
TheStateName1 = row[0]
thecntyName1 = row[4]
idpoly1 = row[5]
idobject1 = row[6]
stateFIPS1 = row[7]
countyFIPS1 = row[8]
fips1 = row[9]
fipSnum1 = row[10]
fipsNumer1 = row[11]
#totarea = row[12]
XPoint = row [13]
YPoint = row[14]
#print Cat
print TheStateName1
print thecntyName1
print row ### do something with that value!
Total_X1 += row[2] *row[3]
print Total_X1
Total_Y1 += row[1] *row[3]
print Total_Y1
TotalPop1 += row[3]
print TotalPop1
print ""
print "X is: " , Total_X1
print "POP is: " , TotalPop1
centroid_X1 = Total_X1/TotalPop1
print "your x centroid is: ",centroid_X1
print ""
#print Cat
print thecntyName1
print TheStateName1
Any Suggestions, Thanks!
The cursor can only 'see' one row at a time, you have to pull info from that row and store it elsewhere.
loc_list = [(row[0], row[1]) for row in arcpy.da.SearchCursor(dataset, ['X_coord', 'Y_coord'])
Will give you a list of X,Y tuples from your attribute table.
After that you've got multiple options for turning that list of tuples into a spatial dataset before calculating the mean - start by reading the ESRI documentation for arcpy.Point and all the related topics linked, and go from there. If you have 10.3 or above you can use Mean Center once you have a point layer.
You'll probably get a wrong answer if you just take the mean of the X and Y without projecting first, so don't.
I get "IndexError: list is out of range" when I input this code. Also, the retmax is set at 614 because that's the total number of results when I make the request. Is there a way to make the retmode equal to the number of results using a variable that changes depending on the search results?
#!/usr/bin/env python
from Bio import Entrez
Entrez.email = "something#gmail.com"
handle1 = Entrez.esearch(db = "nucleotide", term = "dengue full genome", retmax = 614)
record = Entrez.read(handle1)
IdNums = [int(i) for i in record['IdList']]
while i >= 0 and i <= len(IdNums):
handle2 = Entrez.esearch(db = "nucleotide", id = IdNums[i], type = "gb", retmode = "text")
record = Entrez.read(handle2)
print(record)
i += 1
Rather than using a while loop, you can use a for loop...
from Bio import Entrez
Entrez.email = 'youremailaddress'
handle1 = Entrez.esearch(db = 'nucleotide', term = 'dengue full genome', retmax = 614)
record = Entrez.read(handle1)
IdNums = [int(i) for i in record['IdList']]
for i in IdNums:
print(i)
handle2 = Entrez.esearch(db = 'nucleotide', term = 'dengue full genome', id = i, rettype = 'gb', retmode = 'text')
record = Entrez.read(handle2)
print(record)
I ran it on my computer and it seems to work. The for loop solved the out of bounds, and adding the term to handle2 solved the calling error.
I am trying to use a for loop to import data from a list pf file names, the code I am using is as follows:
for n = 2:numfiles
infonew{n} = char(data11{n});
end
FileID = fopen(infonew{n});
allfiles = infonew(2:numfiles)
fclose(FileID);
howmanyfiles = size(allfiles,2);
A = [];
for u = 1:howmanyfiles
fid = fopen(allfiles{u});
end
tline = fgets(fid);
while ischar(tline)
parts = textscan(tline, '%f;');
if numel(parts{1}) > 0
A{u} = [ A{u} ; parts{:}' ];
end
tline = fgets(fid);
end
fclose(fid);
The allfiles is equal to [1x115 char] [1x115 char] [1x115 char] but can vary depending on the number and names of files chosen. Its class is a cell but I am getting the following error:
Cell contents reference from a non-cell array object.
Error in MultiSelectML>MultiSelect_Callback (line 138) A{u} = [ A{u}
; parts{:}' ];
Can anybody suggest a reason for this error? Thanks in advance
It's supposed to save each line in the text file into a list and split it based on commas and categorize them into multiple different lists. The error occurs at the while loop stating that the index is out of range.
lineCounter = 0
j = 0
file = open("savefile.txt","r")
with open('savefile.txt', 'r') as f:
string = [line.strip() for line in f]
for line in file:
lineCounter += 1
while(j<lineCounter):
tempList = string[j].split(',')
firstName[j] = tempList[0]
lastName[j] = tempList[1]
postition[j] = tempList[2]
department[j] = tempList[3]
seniority[j] = tempList[4]
vacationWeeks[j] = tempList[5]
sickDays[j] = tempList[6]
iD[j] = tempList[7]
status[j] = tempList[8]
j += 1
print firstName
file.close() # close the text file
NVM the problem was that the list needed to be appended rather than replaced.
