我想将一个长字符串（特别是一个SQL查询）存储到一个变量中，我希望将其写在更多行上以提高可读性。
如果这很重要，我正在Python 3.5（Anaconda）上使用Jupyter笔记本。
我尝试过：
# SQL query
query = "
SELECT
Sued
,ApplicationNumber_Primary
--,ApprovedLoanAmount, ApprovedLoanDuration, ApprovedMonthlyPayment,
,RequiredLoanDuration, RequiredMonthlyPaymentAmount, RequiredPaidAmount, RequiredCoefficientK1
,ClientFreeSources, ClientTotalIncome, ClientNetIncome, ClientTotalExpenditures
,ClientAgeToApplicationDate, ClientFamilyStatusID, ClientEmploymentDuration, CreditExposure
,CalendarQuarter, MonthOfYear, WeekOfYear, DayOfMonth, DayOfWeek, RegionID, DistrictID, ZIPcodeID
FROM
dbo.vRisk
GO
"
...如我所愿，它不会将字符串存储到变量中。
我们将不胜感激。

尝试使用三引号：
query = """
SELECT
Sued
,ApplicationNumber_Primary
--,ApprovedLoanAmount, ApprovedLoanDuration, ApprovedMonthlyPayment,
,RequiredLoanDuration, RequiredMonthlyPaymentAmount, RequiredPaidAmount, RequiredCoefficientK1
,ClientFreeSources, ClientTotalIncome, ClientNetIncome, ClientTotalExpenditures
,ClientAgeToApplicationDate, ClientFamilyStatusID, ClientEmploymentDuration, CreditExposure
,CalendarQuarter, MonthOfYear, WeekOfYear, DayOfMonth, DayOfWeek, RegionID, DistrictID, ZIPcodeID
FROM
dbo.vRisk
GO
"""

使用多行字符串或在其中插入'\ n'：
this_is_a_multiline_string = """
tata
"""
this_as_well = '''
tata
'''
and_this = "\ntata\n"
Python.org string documentation
and_like_so = ("Some string" # no space after
"that spans lots" # no space after
"of lines" ) # results in 'Some stringthat spans lotsof lines'
