Python文件读取的练习收获分享！
在做如何读取txt文件内容的练习时，遇到了一些问题，后经搜索、分析、学习，觉得有些收获，记录一下，也希望能够帮助到遇到同样问题的同学。两个问题：
1、txt文件中有中文时，会报这个错误
UnicodeDecodeError: 'gbk' codec can't decode byte 0xad in position 87: illegal multibyte sequence
解决方法很简单，在打开文件时加上编码属性即可
with open(dir, 'r',encoding = 'utf-8') as f:
2、文件（f）用 for...in... 结构迭代时，f.readline()的读取问题，大家自己可以分析一下第三个函数 readFileText3()，其实很简单。
程序示例：
def readFileText1(dir):
texts = []
with open(dir, 'r',encoding = 'utf-8') as f:
for line in f:
texts.append(line.strip('\n'))
return texts
#==================================================================
def readFileText2(dir):
texts = []
with open(dir, 'r',encoding = 'utf-8') as f:
for i in range(0, 10):
texts.append(f.readline().strip('\n'))
return texts
#===================================================================
def readFileText3(dir):
texts = []
with open(dir, 'r',encoding = 'utf-8') as f:
for line in f:
texts.append(f.readline().strip('\n'))
return texts
textdir = 'D:\\PythonTest\\IDLE\\testone.txt'
filetexts1 = readFileText1(textdir)
filetexts2 = readFileText2(textdir)
filetexts3 = readFileText3(textdir)
print(filetexts1)
print('=============================================')
print(filetexts2)
print('*********************************************')
print(filetexts3)
运行结果
#运行结果
['dfdfdsfasf', 'sdfweewrewrkl', 'dsf
=============================================
['dfdfdsfasf', 'sdfweewrewrkl', 'dsf
