“How to read the first line of a file in Python” is a fairly common question that every programmer will encounter. So, what are our alternatives? Everything will be made clear to you.
4 ways to read first line of a file in Python”.
We have built-in functions in Python that can handle various file operations. A text file contains a series of strings, each of which is terminated by a newline character \n.
In this guide, we would then read and understand the first line of a text file in Python through some of the following tips.
1) Use the getline()
In this solution, you shoud make use of getline (). Let us learn more about this by using the following example:
import linecache

You may put, use next (). Let us learn more about this by using the following example:
with open("myfile.py") as f:
firstline = next(f)
print(firstline)
Conclusion
