I am importing a CSV file like the one below, using pandas.read_csv
:
df = pd.read_csv(Input, delimiter=";")
Example of CSV file:
10;01.02.2015 16:58;01.02.2015 16:58;-0.59;0.1;-4.39;NotApplicable;0.79;0.2 11;01.02.2015 16:58;01.02.2015 16:58;-0.57;0.2;-2.87;NotApplicable;0.79;0.21
The problem is that when I later on in my code try to use these values I get this error: TypeError: can't multiply sequence by non-int of type 'float'
The error is because the number I’m trying to use is not written with a dot (.
) as a decimal separator but a comma(,
). After manually changing the commas to a dots my program works.
I can’t change the format of my input, and thus have to replace the commas in my DataFrame in order for my code to work, and I want python to do this without the need of doing it manually. Do you have any suggestions?

Answer
pandas.read_csv
has a decimal
parameter for this: doc
I.e. try with:
df = pd.read_csv(Input, delimiter=";", decimal=",")
