python txt文件读取

python txt文件读取

设置文件地址

path = 'D:/硕博/博士生期间资料/机器学习/机器学习课程资料/HW1/data/本纪list格式/高祖本纪.txt'

1. f.read()

with open(path,'r',encoding='utf-8') as f:
    d1 = f.read() #一次性读取txt全部内容,结果是一个str

2. f.readlines()

with open(path,'r',encoding='utf-8') as f1:
    d2 = f1.readlines() #按行读取txt内容,结果是一个list，len(list)=txt行数
print(d2)

3. f.readline()

with open(path,'r',encoding='utf-8') as f2:
    d3 = f2.readline()#只读取txt一行数据,结果是一个str
    print(d3)
    #高祖

可以通过f.readline(size)设置size的值，限定从一行中读取的字符串的个数

with open(path,'r',encoding='utf-8') as f3:
    d4 = f3.readline(1)
d4
#Out[11]: '高'
