Given a string, and we have to append more string (text) at the end of the string using += operator in Python.

给定一个字符串，我们必须在Python中使用+ =运算符在字符串的末尾附加更多字符串(文本)。

There are two methods to add string (text) at the end of the string:

有两种方法可以在字符串末尾添加字符串(文本)：

1. String.append() Method

   String.append()方法

2. By using += operator

   通过使用+ =运算符

String.append() Method: Appends text at the end of the string. Read more: String.append() Method with Example

String.append()方法：在字符串末尾附加文本。 ： 带示例的String.append()方法

Another way is to add text by using +=, this operator concatenates the text in the given string.

另一种方法是使用+ =添加文本，此运算符将给定字符串中的文本连接起来。

Example:

例：

Input:
str: 'New Delhi'
Concatenation of more text 
str += ' ' #space
str += 'Chennai'
str += ' ' #space 
str += 'Mumbai'
str += ' ' #space 
str += 'Bangalore'
Output:
str: 'New Delhi Chennai Mumbai Bangalore'

Program:

程序：

# Python program to add strings 
# to the string 
str = 'New Delhi'
str += ' '    #adding space 
str += 'Chennai'
str += ' '    #adding space
str += 'Mumbai'
str += ' '    #adding space 
str += 'Banglore'
# print the string 
print 'str:',str

Output
