Python Sum excel file
excel, python
Solution
Here is the code for it:
Be sure to look at the comments and post back here if you have any questions (or if I made any mistakes)
import csv
file = open('names.csv', "rb") #Open CSV File in Read Mode
reader = csv.reader(file) #Create reader object which iterates over lines
class Object: #Object to store unique data
def __init__(self, name, produce, amount):
self.name = name
self.produce = produce
self.amount = amount
rownum = 0 #Row Number currently iterating over
list = [] #List to store objects
def checkList(name, produce, amount):
for object in list: #Iterate through list
if object.name == name and object.produce == produce: #Check if name and produce combination exists
object.amount += int(amount) #If it does add to amount variable and break out
return
newObject = Object(name, produce, int(amount)) #Create a new object with new name, produce, and amount
list.append(newObject) #Add to list and break out
for row in reader: #Iterate through all the rows
if rownum == 0: #Store header row seperately to not get confused
header = row
else:
name = row[0] #Store name
produce = row[1] #Store produce
amount = row[2] #Store amount
if len(list) == 0: #Default case if list = 0
newObject = Object(name, produce, int(amount))
list.append(newObject)
else: #If not...
checkList(name, produce, amount)
rownum += 1
for each in list: #Print out result
print each.name, each.produce, each.amount
file.close() #Close file
Problem
I have an excel file that has 3 columns. Please example below ``` Name Produce Number Adam oranges 6 bob Apples 5 Adam Apples 4 steve Peppers 7 bob Peppers 16 Adam oranges 5 ``` I need to generate the sum in python in such a way ``` Name Produce Number Adam oranges 11 bob apples 5 steve peppers 7 etc ``` I am new to python and trying to figure out how to write the output of each persons totals? is there an easy way to gather this data from excel?
