In this program – we are going to learn how can we complete string, print specific characters, print a range of the characters, print string multiple times (using * operator), print multiple stings by concatenating them etc.
在此程序中,我们将学习如何完成字符串 ,打印特定字符,打印字符范围,多次打印字符串(使用*运算符),通过将字符串串联来打印多个字符串等。
Syntax to print string in different ways:
以不同方式打印字符串的语法:
    print (string)          	# printing complete string
print (string[i])       	# printing ith element of string
print (string[i], string[j])# printing ith and jth elements
print (string[i:j])     	# printing elements from ith index to jth index
print (string[i:])      	# printing all elements from ith index
print (string * 2)  	# printing string two times
print (string1 + string2) 	# printing concatenated string1 & string2
Python代码打印字符串字符 (Python code to print string characters)
Here, we have two strings str1 and str2 and we are printing elements in the different ways.
在这里,我们有两个字符串str1和str2,并且以不同的方式打印元素。
# python program to demonstrate example of string
# declaring & initializing two strings
str1 = "IncludeHelp"
str2 = ".com"
print (str1)          		# printing complete str1
print (str1[0])       		# printing 0th (first) elements of str1
print (str1[0], str1[1])	# printing first & second elements
print (str1[2:5])     		# printing elements from 2nd to 5th index
print (str1[1:])      		# printing all elements from 1st index
print (str2 * 2)  		# printing str2 two times
print (str1 + str2) 		# printing concatenated str1 & str2
