Convert string to Float with dot and also comma

Question

This is the column of a dataframe that I have (values are str):

Values
7257.5679
6942.0949714286
5780.0125476250005

This is how I want the record to go to the database:

Values
7.257,56
6.942,09
5.780,01

How can I do this? Thanks in advance!

Answer 1

df["Values"] = df["Values"].apply(lambda x: "{:,.2f}".format(float(x)))

Output:

     Values
0  7,257.57
1  6,942.09
2  5,780.01

To get values in the format 7.257,56. You can make good use of the replace function:

df["Values"] = df["Values"].apply(lambda x: "{:,.2f}".format(float(x)).replace(".", ",").replace(",", ".", 1))

But replace might not be more efficient and concise when dealing with larger dataset, in that case you might want to look into translate, that will be the best approach to go with.

trans_column = str.maketrans(",.", ".,")
df["Values"] = df["Values"].apply(lambda x: "{:,.2f}".format(float(x)).translate(trans_column))

Output:

     Values
0  7.257,57
1  6.942,09
2  5.780,01
