Example 1: Python Read CSV File main.py from csv import reader # open demo.csv file in read mode with open('demo.csv', 'r') as readObj: # pass the file object to reader() to get the reader object csvReader = reader(readObj) # Iterate over each row in the csv using reader obj...
In this code snippet, we again import NumPy and use the loadtxt function to read the CSV file. The parameters are similar to those used in genfromtxt. The delimiter specifies that the data is comma-separated, while skiprows=1 allows us to skip the header row. The primary difference betwee...
Python Parse CSV File Writing a CSV file in Python For writing a file, we have to open it in write mode or append mode. Here, we will append the data to the existing CSV file. import csv row = ['David', 'MCE', '3', '7.8'] row1 = ['Lisa', 'PIE', '3', '9.1'] row...
In this example, skiprows is range(1, 20, 2) and corresponds to the values 1, 3,…, 19. The instances of the Python built-in class range behave like sequences. The first row of the file data.csv is the header row. It has the index 0, so pandas loads it in. The second row ...
