python实现文本创建和读写

path="C:\\Users\\ming\\Desktop\\pydata-book-2nd-edition\\examples\\segismundo.txt"
# 建立新的tep.txt文件并将其放在桌面上
with open('C:\\Users\\ming\\Desktop\\tep.txt','w') as hen:
    hen.writelines(x for x in open(path) if len(x)>1)

# 读取每一行
with open('tep.txt') as f:
    lines=f.readlines()
    print(lines)

# 读取十个字
with open(path) as f:
    chars=f.read(10)
    print(chars)

with open(path,'rb') as f:
    data=f.read(10)
    print(data)
    # 解码
    print(data.decode('utf8'))
