Hướng dẫn how do you check if all elements in a list are strings python? - làm cách nào để kiểm tra xem tất cả các phần tử trong danh sách có phải là chuỗi python không?

Trong bài viết này, chúng tôi sẽ điều chỉnh các cách khác nhau để kiểm tra xem tất cả các yếu tố trong một danh sách nhất định là giống nhau hoặc khớp với một điều kiện.

Giả sử chúng ta có một danh sách chuỗi, tức là.

# List of string 
listOfStrings = ['Hello'] * 10

Bây giờ, hãy để sử dụng hàm python tất cả [] để kiểm tra xem tất cả các phần tử trong danh sách đã cho có giống nhau không.

Python: tất cả [] hàm

Python tất cả [] chức năng kiểm tra xem tất cả các yếu tố của IT có thể được cho là đúng.

Kiểm tra xem phần tử có giống nhau bằng tất cả []

Hãy để chuyển đổi danh sách thành ITable và kiểm tra xem mỗi mục nhập có thể bằng với phần tử đầu tiên của danh sách bằng tất cả [], tức là không.

'''    
    check if element are same using all[]
    It will Iterate through all the elements in list and check if all elements are similar to first element or not.
'''
result = False;
if len[listOfStrings] > 0 :
    result = all[elem == listOfStrings[0] for elem in listOfStrings]

if result :
    print["All Elements in List are Equal"]
else:        
    print["All Elements in List are Not Equal"]

Quảng cáo

Đếm [] Trả về số lượng xuất hiện của phần tử đã cho trong danh sách.

Hãy gọi cho chức năng Count [] của danh sách với phần tử Firts của Danh sách là đối số. & NBSP; Nếu số lần xuất hiện của nó bằng độ dài của danh sách, thì điều đó có nghĩa là tất cả các phần tử trong danh sách là giống nhau.

'''    
    check if element are same using list.count[]
    If occurence count of first element in list is equal to length of list.
    Then it means all elements in List are equal 
'''
result = False;
if len[listOfStrings] > 0 :
    result = listOfStrings.count[listOfStrings[0]] == len[listOfStrings]

Hãy cùng làm điều tương tự trong một dòng, tức là.

result = len[listOfStrings] > 0 and all[elem == listOfStrings[0] for elem in listOfStrings]

Kiểm tra xem tất cả các phần tử có giống nhau bằng cách sử dụng tập hợp không

Vì tập hợp chỉ chứa các phần tử duy nhất, do đó, hãy chuyển đổi danh sách thành SET. & NBSP; Nếu kích thước bộ là 1 thì điều đó có nghĩa là tất cả các phần tử trong danh sách đã cho là giống nhau.

'''    
    As set contains unique elements only, so if list has similar elements, then only one will stored in set.
'''    
result = len[set[listOfStrings]] == 1

Ví dụ hoàn chỉnh như sau,

def main[]:
    
    # List of string 
    listOfStrings = ['Hello'] * 10
    
    # Print the List
    print[listOfStrings]
    
    '''    
        check if element are same using all[]
        It will Iterate through all the elements in list and check if all elements are similar to first element or not.
    '''
    result = False;
    if len[listOfStrings] > 0 :
        result = all[elem == listOfStrings[0] for elem in listOfStrings]    
    
    if result :
        print["All Elements in List are Equal"]
    else:        
        print["All Elements in List are Not Equal"]
    
    '''    
        check if element are same using list.count[]
        If occurence count of first element in list is equal to length of list.
        Then it means all elements in List are equal 
    '''
    result = False;
    if len[listOfStrings] > 0 :
        result = listOfStrings.count[listOfStrings[0]] == len[listOfStrings]
        
    if result :
        print["All Elements in List are Equal"]
    else:        
        print["All Elements in List are Not Equal"]
        
        
    # Do the above logic in single line    
    result = len[listOfStrings] > 0 and all[elem == listOfStrings[0] for elem in listOfStrings] 
       
    if result :
        print["All Elements in List are Equal"]
    else:        
        print["All Elements in List are Not Equal"]      
    
    
    '''    
        As set contains unique elements only, so if list has similar elements, then only one will stored in set.
    '''    
    result = len[set[listOfStrings]] == 1   
    
    if result :
        print["All Elements in List are Equal"]
    else:        
        print["All Elements in List are Not Equal"]      
         
if __name__ == '__main__':
    main[]

Output:

['Hello', 'Hello', 'Hello', 'Hello', 'Hello', 'Hello', 'Hello', 'Hello', 'Hello', 'Hello']
All Elements in List are Equal
All Elements in List are Equal
All Elements in List are Equal
All Elements in List are Equal
& nbsp;
 

Đưa ra một danh sách chỉ chứa các phần tử chuỗi Nhiệm vụ ở đây là viết một chương trình Python để kiểm tra xem tất cả chúng có phải là số hay không. Nếu tất cả đều trả về số đúng khác, hãy trả về sai.

Input : test_list = ["434", "823", "98", "74"]
Output : True
Explanation : All Strings are digits.
Input : test_list = ["434", "82e", "98", "74"]
Output : False
Explanation : e is not digit, hence verdict is False.

Phương pháp 1: Sử dụng tất cả [], isDigit [] và biểu thức máy phátUsing all[], isdigit[] and generator expression

Trong đó, chúng tôi kiểm tra các số từ isDigit []. Tất cả [] được sử dụng để kiểm tra tất cả các chuỗi là số và lần lặp cho mỗi chuỗi được thực hiện bằng cách sử dụng biểu thức máy phát.

Làm thế nào để bạn kiểm tra xem một danh sách chỉ chứa chuỗi?

Sử dụng hàm tất cả [] để kiểm tra xem danh sách chỉ chứa chuỗi, ví dụ: Nếu tất cả [isInstance [mục, str] cho mục trong my_list]:. Hàm tất cả [] sẽ trả về true nếu danh sách chỉ chứa các chuỗi và sai nếu không. Đã sao chép!, e.g. if all[isinstance[item, str] for item in my_list]: . The all[] function will return True if the list contains only strings and False otherwise. Copied!

Làm thế nào để bạn kiểm tra xem tất cả các phần tử trong một chuỗi có giống nhau không?

Bạn có thể chuyển đổi danh sách thành một bộ. Một bộ không thể có bản sao. Vì vậy, nếu tất cả các phần tử trong danh sách ban đầu là giống hệt nhau, tập hợp sẽ chỉ có một yếu tố. Nếu len [set [input_list]] == 1: # input_list có tất cả các yếu tố giống hệt nhau.if len[set[input_list]] == 1: # input_list has all identical elements.

Làm thế nào để bạn kiểm tra xem tất cả các giá trị trong danh sách là Python số?

Phương thức python isNumeric [] Phương thức isNumeric [] trả về true nếu tất cả các ký tự là số [0-9], nếu không thì sai.isnumeric[] Method The isnumeric[] method returns True if all the characters are numeric [0-9], otherwise False.

Làm thế nào để bạn kiểm tra xem một phần tử có trong một chuỗi trăn không?

Cách đơn giản nhất để kiểm tra xem một chuỗi có chứa chuỗi con trong Python là sử dụng toán tử trong không.Điều này sẽ trả về đúng hay sai tùy thuộc vào việc tìm thấy cơ sở được tìm thấy.Ví dụ: câu = 'Có nhiều cây trên Trái đất hơn các ngôi sao trong Dải Ngân hà' Word = 'Galaxy' nếu từ trong câu: in ['từ tìm thấy.use the in operator. This will return True or False depending on whether the substring is found. For example: sentence = 'There are more trees on Earth than stars in the Milky Way galaxy' word = 'galaxy' if word in sentence: print['Word found.
