enum.from_str()
method:Python
In this example, the
string
variable is a string that has the value of"VALUE1"
. TheMyEnum
enum has three values:Value1
,Value2
, andValue3
. Theenum.from_str(MyEnum, string)
method casts thestring
variable to an enum.try-except
block:Python
In this example, the
string
variable is a string that has the value of"VALUE1"
. TheMyEnum
enum has three values:Value1
,Value2
, andValue3
. Thetry-except
block first tries to cast thestring
variable to an enum. If thestring
variable is not a valid enum value, then theValueError
exception is raised.Which method you use depends on your specific needs. If you need to cast a string to an enum and you don't need to do any further processing on the enum value, then the
enum.from_str()
method is a good option. If you need to do further processing on the enum value, then thetry-except
block is a good option.
