Consider the following my_data.txt file:
A,B10%,315%,4
To parse column A as a numeric when using read_csv(~):
df = pd.read_csv("my_data.txt", converters={"A": lambda val : int(val.rstrip("%")) / 100})df
A B0 0.10 31 0.15 4
Here, converters is a dictionary where:
the key is the column to target
the value is the function to apply to each value of the column
