4. Python Variable Names are Case-Sensitive Variables in Python are case sensitive such that Name, name, and NAME will all be considered as three different variables. Example: name = "Learn" Name = "Python Variables" print(name) # output - Learn print(Name) # output - Python Variables #...
This can be useful to inspect global variables or a stack trace when a script raises an exception. -I Run Python in isolated mode. This also implies -E and -s. In isolated mode sys.path contains neither the script's directory nor the user's site-packages directory. All PYTHON* ...
【形参,formal parameter】While defining method, variables passed in the method are called parameters. 【实参,actual parameter】While using those methods, values passed to those variables are called arguments. 再换个说法: 形参(parameter)通常在函数创建时被定义,决定了什么实参(argument)可以被接收。
def outer_function(): scope = "local" def inner_function(): nonlocal scope scope = "nonlocal" print(scope) inner_function() print(scope) Summary Variables are used in every program. They are a type of identifier. We learned how to define a variable, rules associated with it, and how...
