Python 以相反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，让我们首先创建一个名为amit.txt的文本文件，其中包含以下内容

使用切片显示文本文件的内容

示例

现在让我们以相反的顺序读取上述文件的内容−

# 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

通过循环以反向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
