I am trying to do text preprocessing but I found out that one single data in my text column contains float.

i=0
while True:
    for each in list_df['text']:
        print(type(list_df['text'][i]))
        i+=1

enter image description here

How can I change this into str?

    df['text'].astype(str) to cast the entire column to strings. you can check by using apply df['text'].astype(str).apply(type) Commented May 9, 2021 at 22:19

Assuming col_x is your column name, try:

df['col_x'] = df['col_x'].astype(str)
