这里statement1和statement2两个变量都为字符串,但是quantity这个变量为整数,因此print statement1 + quantity + statement2会报错TypeError: cannot concatenate 'str' and 'int' objects, 提示不能将字符串和整数拼接合并。解决的办法是使用str()这个函数将quantity从整数转化为字符串,举例如下: ...
If you want to concatenate variables or a variable and a literal, use +:如果要连接变量或变量和文字，请使用+：>>> prefix + 'thon''Python'Strings can be indexed (subscripted), with the first character having index 0. There is no separate character type; a character is simply a string of...

1、print语法格式 print()``函数具有丰富的功能,详细语法格式如下:print(value, ..., sep=' ',end='\n', file=sys.stdout,flush=False) 默认情况下,将值打印到流或``sys.stdout``。 可选关键字参数: file``:类文件对象(``stream``)``;``默认为当前的``sys.stdout``。
Assign String to a VariableAssigning a string to a variable is done with the variable name followed by an equal sign and the string:Example a = "Hello"print(a) Try it Yourself » Multiline StringsYou can assign a multiline string to a variable by using three quotes:...
print() # Print a newline at the end of the row. # Calculate the next step's cells based on current step's cells: for x in range(WIDTH): for y in range(HEIGHT): # Get neighboring coordinates: # `% WIDTH` ensures leftCoord is always between 0 and WIDTH - 1 ...
Shells typically do their own tokenization, which is why you just write the commands as one long string on the command line. With the Python subprocess module, though, you have to break up the command into tokens manually. For instance, executable names, flags, and arguments will each be ...
In this example, you run the string concatenation, store the result in a variable, and finally have the f-string interpolate that variable’s content. This approach avoids the backslash issue, but it feels like something is wrong with f-strings. Why don’t they allow all valid Python ...
