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: ...
And you can assign thesamevalue to multiple variables in one line. 您可以在一行中为多个变量分配相同的值。 x = y = z = "Orange" print(x) print(y) print(z) Output Variables (输出变量) The Python print statement is often used to output variables. Python 的 print 语句通常用于输出变量。

To create a line plot in Seaborn, we can use one of the two functions: lineplot() or relplot(). Overall, they have a lot of functionality in common, together with identical parameter names. The main difference is that relplot() allows us to create line plots with multiple lines on diffe...
