Importing pandas DataFrame column as string not int

Sometimes we need to import a CSV file and we want the columns as strings, not int, for this purpose while importing the CSV file, we define a dictionary inside the read_csv() method. This dictionary consists of a key that has the column name and the values which have their dtype.

Note

To work with pandas, we need to import pandas package first, below is the syntax:

import pandas as pd

Let us understand with the help of an example,

Python program to import pandas DataFrame column as string not int

# Importing pandas package
import pandas as pd

# Importing a csv file
data = pd.read_csv('D:/mycsv1.csv', dtype={'A':object})

# Creating a DataFrame
df = pd.DataFrame(data)

# Display DataFrame
print("Created DataFrame:\n",df,"\n")

# Check the dtype of each colum
print("Data Types:\n",df.dtypes)
