How do I read a file in Python 3 ?

read()

read() is a python function gets used to reading the content from the file.


fileobject = open("data.csv", "r")
print(fileobject.read())

fileobject.readline() will read entire contents from the csv

if you want to read the part of the line then you need to pass the number of bytes.


fileobject = open("data.csv", "r")
print(fileobject.read(10))

read(10) is used to read 10 bytes from the file.
