Question

Using Python 2.7 and PyCharm CE 2018.2.4, I have the following code:

from datetime import datetime as dt

def updateGroupDynamicBenchmark(self, security, group, runTime):
    """
    Update all the fields in a group from BPipe
    :param security: Security to update
    :type  security: Common.secMasterRecords.SecMasterRecord
    :param group:    Group id to update
    :type  group:    Common.secMasterFieldPolicyMgr.SecMasterFieldGroup
    :param runTime:   Running time for the update
    :type  runTime:   datetime.datetime
    :return:  New expiry time
    :rtype:   datetime.datetime
    """
    return dt.now()

This code generates a warning, appearing on the name of the function in the declaration:

Type hinting is missing for a function definition

What could be done to fix this? Thank you very much

Answer 1

Typehint your function.

Example:

def square(number: int) -> int:
    return number ** 2
