How to TypeError: a bytes-like object is required, not ‘str’ Error Occurs?

Let’s look at a code example that produces the same error.

with open("fruits.txt", "rb") as file:
	fruits = file.readlines()

for r in fruits:
	if "mango" in r:
		print(r)

Output

TypeError: a bytes-like object is required, not 'str'

Binary files are considered a series of bytes data and not as a string. This means that all data read from the file is returned as bytes objects, not str. You cannot then use a string in a containment test:

We can fix this error by opening the file in read-only mode instead of binary mode, as shown below.

with open("fruits.txt", "r") as file:
	fruits = file.readlines()

for r in fruits:
	if "mango" in r:
		print(r)
