分析單個文本

split()方法，是以空格為分隔符將字符串拆分成多個部分，並將這些部分存儲到一個列表中

title = ‘My name is oliver!‘
list = title.split()
print(list)

運行結果如下：

現在存在一個文本如下：

我們要統計這個文本中有多少個字符

file_path = "txt\MyFavoriteFruit.txt"

try:
    with open(file_path) as file_object:
        contents = file_object.read()
except FileNotFoundError:
    msg 
 
= "Sorry,the file does not exist."
    print(msg)
else:
    #計算該文件包含多少個單詞
    words = contents.split()
    num_words = len(words)
    print("The file "+" has about " + str(num_words) +" words.")

分析多個文本

上面只是對單個文本進行分析，那麽我們對多個文本進行分析時，不可能每次都去修改file_path,所以在這裏我們使用函數來進行分析

def count_words(file_path):
    
 
try:
        with open(file_path) as file_object:
            contents = file_object.read()
    except FileNotFoundError:
        msg = "Sorry,the file does not exist."
        print(msg)
    else:
        #計算該文件包含多少個單詞
        words = contents.split()
        num_words = len(words)
        
 
print("The file "+" has about " + str(num_words) +" words.")

#調用函數
file_path="txt\MyFavoriteFruit.txt"
count_words(file_path)

加入現在想對A.txt,B.txt,C.txt三個文件同時統計文件字數，那麽只需要循環調用即可

def count_words(file_path):
    try:
        with open(file_path) as file_object:
            contents = file_object.read()
    except FileNotFoundError:
        msg = "Sorry,the file does not exist."
        print(msg)
    else:
        #計算該文件包含多少個單詞
        words = contents.split()
        num_words = len(words)
        print("The file "+" has about " + str(num_words) +" words.")

#調用函數
file_paths = [‘txt\A.txt‘,‘txt\B.txt‘,‘txt\C.txt‘]
for file_path in file_paths:
    count_words(file_path)

運行結果：
