Sometimes, while working with locations, we need a lot of data which has location points in form of latitutes and longitudes. These can be in form of a string and we desire to get tuple versions of same. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using tuple() + float() + split() + map()
The combination of above functions can be used to perform this task. In this, we first split the two parts of coordinates into a list, apply float function to each of them using float() and map() and lastly it is converted to tuple using tuple().
# Python3 code to demonstrate working of # Convert location coordinates to tuple # Using tuple() + float() + split() + map() # Initializing string test_str = "44.6463, -49.583" # printing original string print("The original string is : " + str(test_str)) # Convert location coordinates to tuple # Using tuple() + float() + split() + map() res = tuple(map(float, test_str.split(', '))) # printing result print("The coordinates after conversion to tuple are : " + str(res)) |
The original string is : 44.6463, -49.583 The coordinates after conversion to tuple are : (44.6463, -49.583)
Method #2 : Using eval()
This is the one-liner and recommended method to perform this particular task. In this, the eval(), internally detects the string and converts to floating point number seperated as tuple elements.
# Python3 code to demonstrate working of # Convert location coordinates to tuple # Using eval() # Initializing string test_str = "44.6463, -49.583" # printing original string print("The original string is : " + str(test_str)) # Convert location coordinates to tuple # Using eval() res = eval(test_str) # printing result print("The coordinates after conversion to tuple are : " + str(res)) |
The original string is : 44.6463, -49.583 The coordinates after conversion to tuple are : (44.6463, -49.583)
