How to identify if a value is integer or number? - robotframework

Question

I want to identify if a value stored in a variable is an integer or not. If its an integer then it should return a Boolean value
I have tried using Built-In functions like Should be Equal As Numbers, Should be Equal As Integers but they did not work.
Since I am not so sound in Python, hence I was not able to make use of the Python built-in functions but I have a strong feeling that python functions like .isdigit() or .isnumeric() can come in handy here.
I am storing some value in a variable, say ${TestVariable}
Now, I have tried identifying the stored value as integer via following ways:
${Status} Run Keyword and Return Status Should be Equal As Numbers ${TestVariable} 1
Log to Console \n ${TestVariable}-${Status}
And I have passed values like
a,b,1,2
Since I have hard coded value 1 in Should Be Equal As Numbers, hence it returned True when the value stored in ${TestVariable} is 1 but returned False when the value was 2
Actual Result:
a-False
b-False
1-True
2-False
Expected Result:
I want Robot to return True when value is a number and False when its a character like below
a-False
b-False
1-True
2-True

Answer 1

Here is a possible solution, please note that "2e10" is converted to number, but the keyword does not consider that.
*** Test Cases***
Verify Types
FOR ${item} IN two ${None} 1235 2.567 2e10
${result}= Check Type ${item}
Log Item ${item} is ${result}
END
*** Keywords ***
Check Type
[Arguments] ${object}
[Documentation] Checks if the ${object } is INTEGER, NUMBER or STRING
Return From Keyword If not "${object}" NONE
${result} ${value}= Run Keyword And Ignore Error Convert To Number ${object}
${isnumber}= Run Keyword And Return Status Should Be Equal As Strings ${object} ${value}
${result} ${value}= Run Keyword And Ignore Error Convert To Integer ${object}
${isinteger}= Run Keyword And Return Status Should Be Equal As Strings ${object} ${value}
Return From Keyword If ${isnumber} NUMBER
Return From Keyword If ${isinteger} INTEGER
Return From Keyword STRING

if type(a) == int:
print('the value is integer')
a = "sabuj"
if type(a) == str:
print('the value is string')
a = [1,2,3]
if type(a) == list:
print('the value is List')
