重要提示:一定要确保CMakeList.txt中#set(CMAKE_BUILD_TYPE Release)这句有的话被注释掉,否则即使在编译的时候即使设置了-DCMAKE_BUILD_TYPE=Debug,调试时一样会无法进入断点。 Ctrl+Shift+P,然后键入tasks: Configure Task, 选择catkin_make:build,会在.vscode文件夹下自动生成文件task.json。 然后Ctrl+Shift+...
codeRose Python(六) 高阶函数 1.map/reduce map()函数接收两个参数,一个是函数,一个是Iterable,map将传入的函数依次作用到序列的每个元素,并把结果作为新的Iterator返回。 把函数f(x)=x*x作用于一个list序列 deff(x):returnx*x r=map(f,[1,2,3,4,5,6])print(list(r)) 控制台输出结果: [1, 4...
Python的for循环不仅可以用在list和tuple,还可以用在其他可迭代对象,比如dict就可以迭代: d={'a':1,'b':2,'c':3}#循环打印keyforkeyind:print(key)#默认循环的是keyforvalueind.values():print(value) 迭代字符串对象: #迭代一个str对象s='adcsddd'forxins:print(x) 只要作用于一个可迭代对象,for循...
