import csv

exampleFile = open(‘C:\\Users\\del\\Desktop\\123.csv‘)
exampleReader = csv.reader(exampleFile)

print(type(exampleReader))  #<class ‘_csv.reader‘>

exampleData = list(exampleReader)          #转换为list列表，这样才方便访问

print(exampleData)
print(‘--------------------------------------1‘)
print(exampleData[0])
print(exampleData[1])
print(exampleData[2])
print(exampleData[3])

print(‘--------------------------------------2‘)

print(exampleData[0][0])
print(exampleData[0][1])
print(exampleData[0][2])

print(‘--------------------------------------3‘)

for row in exampleData:
    print(row)
