print()函数不支持老print语句的“软空格”特性,例如,在python2.x中,print "A\n", "B"会输出"A\nB\n",而python3.0中,print("A\n", "B")会输出"A\n B\n" 学会渐渐习惯print()吧! 使用2to3源码转换工具时,所有的print语句被自动转换成print()函数调用,对大项目,这是无需争论的。 python3.0使用...

What Is Docker? Unpacking This Popular Application Platform You may often hear developers say “But, it works on my machine!” It’s so common that it’s a meme in the dev world. This is because as a code becomes more complex, localdeveloper environmentsdrift further away from the server...
File"", line1, in ValueError:notenoughvaluestounpack(expected2, got0) The syntax which allows a comma separated series of names on the left to unpack the value on the right is known assequence unpackingin python. The reason MockObject is incompatible with sequence unpacking is due to a lim...
Is there a way to pass in a different number of items with each call of the function without wrapping them in a sequence? That’s where args and kwargs come in! But before discussing args and kwargs, we need to briefly review the unpacking operators. ...

You will also learn about unpacking the .tar and .zip files using applications. Chapter 7, Text Processing and Regular Expressions, looks at text processing and regular expressions in Python. Python has a very powerful library of things called called regular expressions, which do tasks such as ...
Hence the syntax error in (a, b = 6, 9). The syntax of the Walrus operator is of the form NAME:= expr, where NAME is a valid identifier, and expr is a valid expression. Hence, iterable packing and unpacking are not supported which means, (a := 6, 9) is equivalent to ((a :...
