Python字符串连接：使用+运算符连接两个字符串

In most of the programming language, we use plus operator (+) to concatenate two strings. Same as + Operator can also be used in Python to concatenate two strings in Python programming language.

在大多数编程语言中，我们使用加号(+)来连接两个字符串 。 与+运算符相同，也可以在Python中使用Python编程语言来连接两个字符串。

In this program, there are two strings "Hello" and "World" and we have to concatenate these two strings along with a space between the strings and assign result to third string.

在此程序中，有两个字符串“ Hello”和“ World” ，我们必须将这两个字符串以及两个字符串之间的空格连接起来，然后将结果分配给第三个字符串。

Example:

例：

Input:

str1 = "Hello"

str2 = "World"

str3 = str1 + ' ' + str2

Output:

str3 = "Hello World"

Program:

程序：

# Python program of concatenate operator

# input strings

str1 = "Hello"

str2 = "World"

# concatenate and assign in another string

str3 = str1 + ' ' + str2

# print strings

print "str1: ",str1

print "str2: ",str2

print "str3: ",str3

[/code]

Output
