TypeError: 'str' object cannot be interpreted as an integer python for loop
问题
我正在尝试创建一个函数，该函数从给定的年份和月份开始返回数据，直到今天的年份和月份。为了简单起见，我已经用外部循环和内部循环的打印语句代替了我希望函数执行的操作。我收到了错误消息TypeError: 'str'对象无法解释为整数
定义函数
def frequency_database(df, start_month, start_year):
data = pd.DataFrame([])
import datetime
start_month = int(start_month)
start_year = int(start_year)
today = datetime.date.today()
today_year = today.strftime('%Y')
for y in range(start_year, today_year):
print('Outer loop enter for year', y)
# 这里是我想要执行的某些操作.............
for x in range(start_month, 13):
print('Inner loop enter for month number', x)
# 这里是我想要执行的某些操作.............
调用函数
frequency_database(df, 1, 2015)
错误
TypeError: 'str'对象无法解释为整数

答案1
得分: 5
问题是你尝试将range赋予一个str，即today_year=today.strftime('%Y')。
只需将以下行
today_year=today.strftime('%Y')
替换为
today_year=int(today.strftime('%Y'))
正如Stargazer所指出的，你也可以这样做：
today_year = today.year
而不必将str转换为int。
英文:
The problem is you tried to give range a str which is today_year=today.strftime('%Y').
Just replace the line
today_year=today.strftime('%Y')
with
today_year=int(today.strftime('%Y'))
As pointed out by Stargazer, you could do,
today_year = today.year
instead of converting the str to int
