Write mode ('w'): This mode is used to write to a file. It will create a new file if the file does not exist, and overwrite the file if it does exist. Append mode ('a'): This mode is used to add new data to the end of an existing file (append to a file). If the file...
Each module has its own private symbol table, which is used as the global symbol table by all functions defined in the module. Thus, the author of a module can use global variables in the module without worrying about accidental clashes with a user’s global variables. On the other hand, ...
Lambda vs def Function in Python Lambda and def both are keywords that are used to define functions in Python. However, their structure and use cases are different from each other. We have discussed some of the differences between lambda functions and def functions below: Feature Lambda def Def...
