python 文件打开、读、关闭练习

一、题目要求

二、代码实现

f = open("D:\\workspace\\word.txt" , "r", encoding= "UTF-8")

# 方案一
# content = f.read()
# count = content.count("itheima")
# print(f"itmeiha在文件中出现了：{count}次")

# 方案二
num = 0
for line in f:
    line = line.strip()  
# 去除开头结尾的空格及换行符 （输出结果每行最后都加上了" \n "）
    words = line.split(" ")
    for word in words:
        if word == "itheima":
            num += 1

print(num)
f.close()
