Why does the error occur when the value of of position is anything else than 1?

def sumarentradas(self, position):
        global dfEquipoLocal
        dfEquipoLocal.iat[position:2]  = 1
        dfEquipoLocal.iat[position:5]  = 1
        return dfEquipoLocal

I have checked the type of value of position and it remains as an integer, so why wont it allow me to increment the value?

Pay attantion on the documentation with examples

Access a single value for a row/column pair by integer position.

Using this sintax [position:2] you are trying to get a slice instead of a single value from DataFrame. I guess [position, 2] meant to be here.

from the docs of iat it explains that only single values are allowed

Similar to iloc, in that both provide integer-based lookups. Use iat if you only need to get or set a single value in a DataFrame or Series.
