This method will return True if the path points to a regular file or a symbolic link pointing to a regular file, and False otherwise. Moreover, it may also return False, if the path doesn’t exist or is a broken symbolic link. Note that from version 3.8 it returns False if the file...
Implicit Boolean Evaluation:In Python, empty strings, empty lists, and similar objects are considered “falsy” in a boolean context. Usingif not my_string:implicitly checks if the string is empty or evaluates toFalse. It’s a more idiomatic way to check for emptiness. Versatility:Theif not ...
try:f=open("filename.txt")exceptFileNotFoundError:# doesn’t existelse:# exists Note: In Python 2 this was anIOError. Useos.path.isfile(),os.path.isdir(), oros.path.exists()¶ If you don’t want to raise an Exception, or you don’t even need to open a file and just need...
Thetry-exceptbranches are working similarly to anif-else statement. Pythontryto open the file, and if it works, append 'New Session'. Python will enter theexceptstatement if aFileNotFoundErroris thrown. This means the file doesn't exist, so we create a new one. ...

Checking if Either Exist Another way to check if a path exists (as long as you don't care if the path points to a file or directory) is to useos.path.exists. importos os.path.exists('./file.txt')# Trueos.path.exists('./link.txt')# Trueos.path.exists('./fake.txt')# Falseos...
Python’s in and not in operators allow you to quickly check if a given value is or isn’t part of a collection of values. This type of check is generally known as a membership test in Python. Therefore, these operators are known as membership operators....
