在Python中,循环打印文件的操作可以通过以下技巧实现:
with
语句打开文件,并利用 for
循环逐行读取和打印文件内容:with open('file.txt', 'r') as file:
for line in file:
print(line)
readlines()
方法一次性读取文件的所有行,并利用 for
循环逐行打印:with open('file.txt', 'r') as file:
lines = file.readlines()
for line in lines:
print(line)
readline()
方法逐行读取文件内容,并在循环中打印:with open('file.txt', 'r') as file:
line = file.readline()
while line:
print(line)
line = file.readline()
read()
方法一次性读取整个文件内容,并在循环中打印:with open('file.txt', 'r') as file:
content = file.read()
print(content)
这些技巧可以让你灵活地操作文件内容,并通过循环打印文件的内容。
