我正在尝试找出如何使下面的代码排除第[9]行有空条目的任何实例。当前csv文件为每一行输出,这将导致行中的“Dad”项为空。我希望输出csv文件不包括任何“Dad”列(第[9]行)为空的行。。。你知道吗
非常感谢您的帮助!你知道吗
def guardiansfather():
with open('hallpass_raw.csv') as csv_file:
csv_reader = csv.reader(csv_file, delimiter=',')
with open('outputfiles/guardians_father.csv', mode='w', newline='') as output_file:
write = csv.writer(output_file, delimiter=',', quoting=csv.QUOTE_MINIMAL)
for row in csv_reader:
a = row[0]
b = row[1]
c = row[2]
studentnumber = row[3]
firstname = row[4]
middlename = row[5]
lastname = row[6]
teacher = row[7]
idnumber = row[8]
father = row[9]
mother = row[10]
guardianemail = row[11]
phone = row[12]
fatheremail = row[13]
motheremail = row[14]
guardianphone = row[15]
schoolname = 'NAME OF SCHOOL'
relationship = 'Father'
father_first = father.split(sep=','[0])
father_last = father.split(sep=', '[1])
write.writerow([schoolname, studentnumber, father_first, father_last, relationship, phone, fatheremail])
使用
if
语句您可以使用
pandas
库:1.)将csv读入数据框:
示例:假设您的数据帧是这样的。你知道吗
2.)删除特定列为
NULL
的行:要删除在列
age
中具有NULL
值的行:你可以看到第二排被放下了。你知道吗
3.)将处理后的数据帧写回csv:
这样,您就不必担心处理csv的复杂循环。你知道吗
