Python allows you to assign values to multiple variables in one line. Python 允许您在一行中为多个变量赋值。 x, y, z = "Orange", "Banana", "Cherry" print(x) print(y) print(z) And you can assign the same value to multiple variables in one line. 您可以在一行中为多个变量分配相同的值...
It is possible to assign multiple variables in a single line. As shown in the code below, it is valid to assign one or more values to multiple variables simultaneously. However, when assigning multiple values to multiple variables, it is essential to ensure that the number of values matches ...
PEP 8: multiple statements on one line (colon) 解决方法:多行语句写到一行了,比如:if x == 2: print('OK')要分成两行写 PEP 8: line too long (82 > 79 characters) 解决方法:超过了每行的最大长度限制79 PEP 8: Simplify chained comparison 可简化连锁比较(例如:if a >= 0 and a <= 9: ...

PEP 8: multiple imports on one line 解决方法:不要在一句 import 中引用多个库,举例:import socket,urllib.error最好写成:import socket import urllib.error PEP 8: blank line at end of line 解决方法:代码末尾行多了空格,删除空格即可 PEP 8: at least two spaces before inline comment ...
We'll cover some of the other functions that are built into Python later in this module, and we'll cover user-defined functions in a later module.You don't have to define variables one at a time. You can define multiple variables on a single line:Python Copy ...

Now check the individual value in Python Shell. >>> x = y = z = 1 >>> print(x) 1 >>> print(y) 1 >>> print(z) 1 >>> Alternatively, you can assign multiple values to multiple variables in a single line. Syntax: , , ..., = <expr>, <expr>, ..., <expr> Example: ...
In the example above, the variablejwas assigned to the string"shark", the variablekwas assigned to the float2.05, and the variablelwas assigned to the integer15. This approach to assigning multiple variables to multiple values in one line can keep your lines of code down, but make sure you...
