Trouble concatenating floats and strings in Python

问题

I'm using this code:

  1. for each in x:
  2. descrVar = descrVar + " " + str(df.iloc[counter, each])

to iterate through a table and concatenate cells into a variable. The problem is, some of the cells will be a NaN. As a result, I'm getting the following error:

  1. TypeError: can only concatenate str (not "numpy.float64") to str

I assume this means a NaN is a float64 and not a str. Is there any way around this, such as forcing every cell to convert to a str?

An f-string will format your data as str.

  1. for each in x:
  2. descrVar += f" {df.iloc[counter,each]}"
