Suppose you have more than one tuple and want to concatenate them all. There are multiple ways to do this in Python, which are discussed below. Concatenate Two Tuples in Python Using Plus Operator (+) You can concatenate the two tuples using the arithmetic operator‘+’, called plus. The...
Return True if the string is a whitespace string, False otherwise. A string is whitespace if all characters in the string are whitespace and there is at least one character in the string. """ pass def istitle(self, *args, **kwargs): # real signature unknown """ Return True if the s...
We can usejoin() functionto concatenate string with a separator. It’s useful when we have a sequence of strings, for examplelistortupleof strings. If you don’t want a separator, then use join() function with an empty string. s1 = 'Hello' s2 = 'World' print('Concatenated String usi...
strftime(format[, tuple]) -> string 1. 【代码说明】 参数format表示格式化日期的特殊字符。例如,“%Y-%m-%d”相当于Java中的“yyyy-MM-dd”。 参数tuple表示需要转换的时间,用元组存储。元组中的元素分别表示年、月、日、时、分、秒。 函数返回一个表示时间的字符串。 参数format格式化日期的常用标记如下所...

Example 2:If we want space between two strings while concatenating, we either have to include a space in the string itself or concatenate the space. 示例2:如果在连接时希望两个字符串之间有空格,我们要么必须在字符串本身中包含一个空格,要么将其串联。
string2 = "Engineer" # using the comma to concatenate two strings together print(string1, string2) From the output, two strings,“string1”and“string2”, are concatenated using the comma“,”within theprint()function. As a result, it returns a string like this:“Software Engineer”. ...

Here is Python code to access some elements of a:>>> a[0] 'foo' >>> a[2] 'baz' >>> a[5] 'corge' Virtually everything about string indexing works similarly for lists. For example, a negative list index counts from the end of the list:...
