print()函数可以同时输出多个变量print()函数的详细语法格式如下:print (value,...,sep='',end='\n',file=sys.stdout,flush=False)从上面可以看出,values参数可以接受任意多个变量或值,因此print()函数完全可以输出多个值。例子:1 user_name = '李四' 2 user_age = 18 3 print("姓名:" ...
多变量线性回归(Linear Regression with multiple variables) (1) 多维特征 & 多变量梯度下降 (2)多维梯度下降的例子:特征缩放(Feature Scaling) (3)学习率(Learning rate) (4)正规方程(Normal equation) (5)python代码实现 学习完了机器学习的多变量线性回归课程,现在来将所学记录下来。
When referring to multiple variables parenthesis is used. Example: str1 = 'World' str2 = ':' print("Python %s %s" %(str1,str2)) Output: Python World : Repeating Characters Use multiplication with strings to repeat characters: print('#' * 10) # Output: ### Other Examples...
Python allows you to assign values to multiple variables in one line:ExampleGet your own Python Server x, y, z = "Orange", "Banana", "Cherry"print(x)print(y)print(z) Try it Yourself » Note: Make sure the number of variables matches the number of values, or else you will get ...
The calls to print() are intended to show how you can access variables from different scopes inside a function. Here’s how this function works: Python >>> from scopes import outer_func >>> outer_func() Hi from the 'local' scope! Hi from the 'nonlocal' scope! Hi from the 'global...

>>> print(y) 1 >>> print(z) 1 >>> Alternatively, you can assign multiple values to multiple variables in a single line. Syntax: , , ..., = <expr>, <expr>, ..., <expr> Example: x, y, z = 1, 2, "abcd" In the above example...
