The assignment is done using the equal (=) operator. Some examples of legal python variables are – = 1 j = 2 Multiple Variable Assignment: You can assign a single value to the multiple variables as follows – a=2 Also, we can assign multiple values to the multiple variables as follows...
这里还有一些例子: >>># 3 into integer myint>>>myint =3>>># a string of characters into a string variable>>>text ='Some text'>>># a floating point number>>>cost =3*123.45>>># a longer string>>>Name ='Mr'+' '+'Fred'+' '+'Bloggs'>>># a list>>>shoppingList = ['ham',...
尝试修改字符串的某个字符会引发TypeError: try: string = " immutable" string[0] = 'I' # 这将会抛出异常 except TypeError as e: print(e) # 输出: 'str' object does not support item assignment 2.3 字符串索引与切片 你可以通过索引来访问字符串中的单个字符,或者使用切片来获取子字符串: greeting ...
Single and double quotes assign a single-line string, and triple quotes assign a multiline string.Note: You can also use triple-double quotes to create a string variable with a multiline string.Read Also Python StringsExample to create string variables...
#Using a backslash for a multiline statement course_name = "Python for " + \ "Data Science at Intellipaat" print(course_name) Output: Explanation: Here, each print statement is written in a separate physical line, while the variable course_name combines multiple physical lines into a singl...
这可能是最简单的例子:当late被传递给if语句时,late充当条件表达式,在布尔上下文中进行评估(就像我们调用bool(late)一样)。如果评估的结果是True,那么我们就进入if语句后面的代码体。请注意,print指令是缩进的:这意味着它属于由if子句定义的作用域。执行这段代码会产生: ...
multiline string that also worksasa multiline comment.""" 如果您的注释跨越多行,最好使用单个多行注释,而不是几个连续的单行注释,这样更难阅读,如下所示: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 """This is a good way to write a comment ...
More than one space around an assignment (or other) operator to align it with another. Yes: x = 1 y = 2 long_variable = 3 1. 2. 3. No: x = 1 y = 2 long_variable = 3 1. 2. 3. Other Recommendations Avoid trailing whitespace anywhere. Because it’s usually invisible, it can...
A common use of the conditional expression is to select variable assignment. For example, suppose you want to find the larger of two numbers. Of course, there is a built-in function, max(), that does just this (and more) that you could use. But suppose you want to write your own co...
Incompatible types in assignment (expression has type "float", variable has type "int") Found 1 error in 1 file (checked 1 source file) 1. 2. 3. 如果没有问题,类型检查器不输出任何内容,如果有问题,则输出错误消息。在这个example.py文件中,第 171 行有一个问题,因为一个名为spam的变量有一个...
