试图在python中找到csv文件中的空白列

Question

import csv 

f = open('E:\pythontest\ip_data.csv') 
csv_f = csv.reader(f) 
for row in csv_f: 
    row_count = sum(1 for row in csv_f) + 1 

print row_count  

现在我试图找到有空格的列并对它们进行计数。

Answer 1

如何如下：

import csv 

dict_count = {} 
count = 0 

with open ("E:\pythontest\ip_data.csv", 'r') as f: 
reader = csv.DictReader(f) 
data = list(reader) 
fields = reader.fieldnames 

for field in range(len(fields)): 
for k,v in data[field].items(): 
    if v is "": 
    dict_count[k] = str(count + 1) 

for k,v in dict_count.items(): 
print k,v
