The readline method
The readline method reads a file and returns its first line. The optional parameter of the method can be used to specify the number of bytes of the file that we need to read.
Syntax
file.readline([number of bytes in a file])
Example
Let's open the file file.txt using the open function, and then read its first line:
res = open('file.txt', 'r')
print(res.readline())
The result of the executed code:
text
