Python - 以相反的顺序显示文本文件的内容?
我们将以相反的顺序显示文本文件的内容。为此,让我们首先使用以下内容创建一个文本文件 amit.txt:
使用切片以相反的顺序显示文本文件的内容
示例
现在让我们以相反的顺序来读取以上文件的内容:
# The file to be read with open("amit.txt", "r") as myfile: my_data = myfile.read() # Reversing the data by passing -1 for [start: end: step] rev_data = my_data[::-1] # Displaying the reversed data print("Reversed data = ",rev_data)
输出
Reversed data = !tisisihT
通过循环以相反的顺序显示文本文件的内容
示例
# Opening the file to read my_data = open('amit.txt','r') # reversing the data for myLine in my_data: l = len(myLine) rev_data = '' while(l>=1): rev_data = rev_data + myLine[l-1] l=l-1 print("Reversed data = ",rev_data) # Displaying the reversed data
输出
Reversed data = !tisisihT
