for循环遍历字典的其他方法 除了使用items()方法外,还可以使用keys()和values()方法来遍历字典中的键和值。 使用keys()方法遍历字典中的键: AI检测代码解析 forkeyinmy_dict.keys():print(key) 1. 2. 使用values()方法遍历字典中的值: AI检测代码解析 forvalueinmy_dict.values():print(value) 1. 2. ...
1 i={ 2 'status': 'success', 3 'country': '中国', 4 'countryCode': 'CN', 5 'region': 'BJ' 6 } 7 for a in i: 8 print(a) 4.在字典后加.values()可以显示值,但是不显示关键词 1 i={ 2 'status': 'success', 3 'country': '中国', 4 'countryCode': 'CN', 5 'region'...
python json dictionary for-loop 我想迭代items中的所有项和band中的所有band(在item对象中)。但只有外部for循环有效,并且仅适用于第一项。知道为什么吗? from satsearch import Search from IPython.display import JSON import json # configuration url = 'https://earth-search.aws.element84.com/v0' # URL ...
Python stringis a sequence of characters. If within any of your programming applications, you need to go over the characters of a string individually, you can use the for loop here. Here’s how that would work out for you. word="anaconda"forletterinword:print(letter) ...
一起使用Python里for循环和dictionary字典 工具/原料 Python 方法/步骤 1 新建一个空白的PYTHON文档。2 先定义一个字典的内容，并且打印看看有没有错误。person = { "Peter": "funny", "Jence": "Super", "Alice": "Crazy", "Ben": "Smart",}print(person)3 如果直接运用FOR循环，那么只会把关键...
for_loop_dictionary.py #!/usr/bin/python data = { "de": "Germany", "sk": "Slovakia", "hu": "Hungary", "ru": "Russia" } for k, v in data.items(): print(f"{k} is an abbreviation for {v}") The code example prints the keys and the values of the Python dictionary. ...
2. Simple One Line For Loop in Python Use for loop to iterate through an iterable object such as alist,set,tuple,string,dictionary, etc., or a sequence. This iteration process is done in one-line code this is the basic way to write for loop in one line. ...
In contrast, the Python while loop repeats as long as a certain condition is true. This tutorial describes how to use both types of loops and explains how to use Python for common scenarios like looping through a dictionary. An Introduction to Python for and while Loops The Python for ...
This means thatfor x in dictis shorthand forfor x in dict.iterkeys(). 在python3中,不再支持dict.iterkeys()、dict.itervalues()和dict.iteritems()。而是使用dict.keys()、dict.values()和dict.items()。 相关讨论 在python3中,不再支持dict.iterkeys()、dict.itervalues()和dict.iteritems()。而是使用...
