I am trying to load stock market data csv file in a jupyter note book using import numpy as np How to Fix in Python: ‘numpy.ndarray’ object is not callable The following tutorials explain how to fix other common errors in Python: Notice that we’re able to convert the revenue column from a string to a float and we don’t receive any error since we removed the dollar signs before performing the conversion. The way to resolve this error is to use the replace() function to replace the dollar signs in the revenue column with nothing before performing the conversion: #convert revenue column to floatĭf = df. We receive an error since the revenue column contains a dollar sign in the strings. ValueError : could not convert string to float: '$400.42' Now suppose we attempt to convert the revenue column from a string to a float: #attempt to convert 'revenue' from string to floatĭf = df. Suppose we have the following pandas DataFrame: import pandas as pdĭf = pd. The following example shows how to resolve this error in practice. When this occurs, you must first remove these characters from the string before converting it to a float. This error usually occurs when you attempt to convert a string to a float in pandas, yet the string contains one or more of the following: One common error you may encounter when using pandas is: ValueError : could not convert string to float: '$400.42'
