As we can see the codes above, the second method involves a new variables 'temp' while the first method not, so the second method is slower than the first method.
Swap Two Values Using a Temporary Variable in Python In this method, a temporary variable is used to swap two values. Consider two variables,aandband a temporary variable,temp. First, the value ofawill be copied totemp. Then the value ofbwill be assigned toa. Lastly, the value oftempwill...
print(f"Hi,I'm{name}.I'm from {country}. And I'm {age}.") #只需要在括号开头写一个f,花括号中的内容就会被自动的替换成指定表达式的值 #注意是表达式 比如{age+1},python将会把表达式运行的结果也就是29替换在字符串中。 #由于这里是任意的表达式,你甚至可以调用一个函数返回一个数值,并替换在...
