os.getcwd and os.path.dirname(_file__) difference

I want to know the difference between the two, just like the title. The result of executing the code is

print(_file__)
print(os.path.dirname(__file__))
print(os.getcwd())

C:/Users/Desktop/pythonedit/API/api df.py
C:/Users/Desktop/pythonedit/API
C:\Users\Desktop\pythonedit\API

I know the location and name of the file that the first one ran. What is the difference between os.path.dirname(file) and os.getcwd()?
