Python3.5 函式的呼叫
望共同進步

寫函式的定義的時候其實已經呼叫了函式,如
#coding:utf-8 #python 3.5.1 def get_Square(x): return x**2 #冪的符號用**(兩個星號表示) result = get_Square(5) print(result)
裡的result = get_Square(5) 就是呼叫了函式get_Square(),然後把返回的值賦給了變數result;那麼我們發現要呼叫一個函式,需要知道函式的名稱
其實Python內建了很多有用的函式,我們可以直接呼叫:
##coding:utf-8 #python 3.5.1 print('abs(-10):',abs(-10)) print('min(1,2,-5,10):',min(1,2,-5,10))
#結果
abs(-10): 10
min(1,2,-5,10): -5
如下是 M_f_def.py 中的程式碼:
#coding:utf-8 #python3.5.1 import requests from bs4 import BeautifulSoup headers = { 'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36'} #定義函式(傳入引數url) def get_Soup(url): response = requests.get(url,headers = headers,timeout = 120) response.encoding = 'utf-8' res = response.text soup = BeautifulSoup(res,'html.parser') return soup #返回soup #呼叫函式
建立一個檔案M_f_call.py ,開始匯入.py檔案,再呼叫函式,如下
#coding:utf-8 #python 3.5.1 importM_function.M_f_def as Fuc import Calcs.calc1 as calcu #這裡呼叫了.calc1.py檔案,結合下面的PS看 soup = Fuc.get_Soup(url = 'http://blog.csdn.net/weixin_39701039/article/details/79563012') print(soup)
#結果:
PS:注意M_f_call.py 檔案要和 M_function在同一個資料夾下(不一定在M_function裡),如下圖:
望有所幫助,望採納!!
