len() function, numbers doesn't work with Geany Editor

[Penguin827]

HI all,


i am a beginner and study python via Geany.
I encounter the below issues.
when i input the code in Geany and run the program,the geany show nothing
E.g

name=["Karen","John","May","Philips")
len(name)
15/3

But if i use the print function, the output (number) can be showed

name=["Karen","John","May","Philips")
len(name)
print(len(name))
4
print(15/3)
5

besides, if i run the Python 3.8 directly
the same code, it can show the number

name=["Karen","John","May","Philips")
len(name)
4
15/3
5

please help me. i cant run the outcome which include numbers in Geany. Thx
