Replace comma and dot in Pandas
21,810
You can use regular expressions to make your conditions general that would work in all cases:
# Make example dataframe for showing answer
df = pd.DataFrame({'Value':['3.4500,00 EUR', '88.782,21 DOLLAR']})
Value
0 3.4500,00 EUR
1 88.782,21 DOLLAR
Use str.replace
with regular expression:
df['Value'].str.replace('[A-Za-z]', '').str.replace(',', '.').astype(float)
0 34500.00
1 88782.21
Name: Value, dtype: float64
Explanation:
-
str.replace('[A-Za-z\.]', '')
removes all alphabetic characters and dots. -
str.replace(',', '.')
replaces the comma for a dot -
astype(float)
converts it from object (string) type to float

I have a Column with data like 3.4500,00 EUR. Now I want to compare this with another column having float numbers like 4000.00. How do i take this string, remove the EUR and replace comma with decimal and then convert into float to compare.
