Python Program To Convert dictionary values to Strings

• Last Updated : 02 Feb, 2021

Given dictionary with mixed data types as values, the task is to write a Python program to convert to parsed strings by different delims.

Examples:

Input : test_dict = {‘Gfg’ : 4, ‘is’ : “1”, ‘best’ : [8, 10], ‘geek’ : (10, 11, 2)}, list_delim, tuple_delim = ‘-‘, ‘^’

Output : {‘Gfg’: ‘4’, ‘is’: ‘1’, ‘best’: ‘8-10’, ‘geek’: ’10^11^2′}

Explanation : List elements are joined by -, tuples by ^ symbol.

Input : test_dict = {‘Gfg’ : 4, ‘is’ : “1”, ‘best’ : [8, 10], ‘geek’ : (10, 11, 2)}, list_delim, tuple_delim = ‘*’, ‘,’

Output : {‘Gfg’: ‘4’, ‘is’: ‘1’, ‘best’: ‘8*10’, ‘geek’: ‘10,11,2’}

Explanation : List elements are joined by *, tuples by , symbol.

Example: Using loop + isinstance() + join()

In this, we check for all the values data types using isinstance() and join using join() for difference delims, converting to parsed strings.

Python3

 # Python3 code to demonstrate working of# Convert dictionary values to Strings# Using loop + isinstance()  # initializing dictionarytest_dict = {'Gfg' : 4,             'is' : "1",             'best' : [8, 10],             'geek' : (10, 11, 2)}               # printing original dictionaryprint("The original dictionary is : " + str(test_dict))  # initializing delimslist_delim, tuple_delim = '-', '^'  res = dict()for sub in test_dict:          # checking data types    if isinstance(test_dict[sub], list):        res[sub] = list_delim.join([str(ele) for ele in test_dict[sub]])    elif isinstance(test_dict[sub], tuple):        res[sub] = tuple_delim.join(list([str(ele) for ele in test_dict[sub]]))    else:      res[sub] = str(test_dict[sub])  # printing resultprint("The converted dictionary : " + str(res))

Output:

The original dictionary is : {‘Gfg’: 4, ‘is’: ‘1’, ‘best’: [8, 10], ‘geek’: (10, 11, 2)}

The converted dictionary : {‘Gfg’: ‘4’, ‘is’: ‘1’, ‘best’: ‘8-10’, ‘geek’: ’10^11^2′}
