*args: arguments 参数 sep: separator 分隔符, 用来间隔多个对象,其默认值时空格。 end: end 结尾,用来设定以什么结尾。默认值是换行符 \n,我们可以换成其他字符。 file:要写入的文件对象。 在Python程序中,在print中也可以同时使用多个字符串,使用“,”隔开,就可以连成一串输出。 print("Hello World") #字符...
Finally, we print out the result using the print() function. We use string concatenation to construct a message that includes the original input values as well as the result. The print() function can take multiple arguments, which are separated by commas. In this case, we’re using commas ...
1.sys.argv 使用方法第一步: import sys 使用方法第二步: temp=sys.argv[1] 【在这里解释一下哦,sys.argv序列中索引0对应的是Python脚本名,剩下的才是传进来的变量】如下代码将会打印Python文件名与你传进去的参数(不传参接收的话会报错) import sys n1=sys.argv[0] n2=sys.argv[1] print(n1,type(n1...
In Python, you can display data to the console with the print() function.To display objects to the console, you pass them as a comma-separated list of arguments to print(). By default, the output that print() produces separates objects by a single space and appends a newline to the ...
