how to use for loop to iterating url index to collect the data

Question

I am a newbie in python. I want to write a for loop to iterate the index in order to pull the data.

Here is my code:

url90=[]
for i in range(-90,0):
 url90.append('http://staging.foglogic.com/api/v1/index.php/accounts/34/reports/bcjobs?cmd=json&datestr=today&**index=i**&filter={}&filterOverride=0&su=1')

I want index=i which from range(-90,0), however the python consider my i as a string instead of a integer.

my result give me 90 identical url :

'http://staging.foglogic.com/api/v1/index.php/accounts/34/reports/bcjobs?cmd=json&datestr=today&index=i&filter={}&filterOverride=0&su=1'

Is there anyone can help me to solve the problem?

Thank you!

如果您认为i变量将自动用于填充列表的字符串中，那么您错了。它不起作用。使用.format：

url90=[]
for i in range(-90,0):
    url90.append('http://staging.foglogic.com/api/v1/index.php/accounts/34/reports/bcjobs?cmd=json&datestr=today&index={0}&filter={{}}&filterOverride=0&su=1'.format(i))
print("\n".join(url90))

请参阅Python demo

请注意，格式字符串中的文字{和}必须加倍（请参阅index={0}）。 {0}是i变量的占位符（请参阅filter={{}}），该变量是该方法的第一个也是唯一的参数。
