I just want to know how to parse a float string to a float, and (separately) an int string to an int. It's good that you ask to do these separately.
Jun 23, 2019 · There is no typecast and no type coercion in Python. You have to convert your variable in an explicit way. To convert an object into a string you use the str() function. It works with any object that has a method called __str__() defined. In fact. str(a) is equivalent to. a.__str__() The same if you want to convert something to int, float, etc.
Dec 8, 2013 · The best way is to enter the entire string of numbers line by line and split them into integers. Here is the Python 3 version: a = [] p = input() p = p.split() for i in p: a.append(int(i)) You can also use list comprehensions: p = input().split("whatever the seperator is") To convert all input from string to int we do the following:
Jul 30, 2022 · @Max the 16 is for base 16.Normally people use base 10 (and in Python there's an implicit 10 when you don't pass a second argument to int()), where you start at 0 then count up 0123456789 (10 digits in total) before going back to 0 and adding 1 to the next units place.
There are several methods to convert string numbers in a list to integers. In Python 2.x you can use the map function: >>> results = ['1', '2', '3'] >>> results = map(int, results) >>> results [1, 2, 3]
def convertStr(s): """Convert string to either int or float.""" try: ret = int(s) except ValueError: #Try float. ret = float(s) return ret That way if the int conversion doesn't work, you'll get a float returned.

Mar 16, 2011 · newlist = [] # Make an empty list for i in list: # Loop to hv a dict in list s = {} # Make an empty dict to store new dict data for k in i.keys(): # To get keys in the dict of the list s[k] = int(i[k]) # Change the values from string to int by int func newlist.append(s) # To add the new dict with integer to the list
Jul 8, 2010 · str is meant to produce a string representation of the object's data. If you're writing your own class and you want str to work for you, add:
I want to convert to int without using loops - for this I use ID.astype(int). The problem is that some of my lines contain dirty data which cannot be converted to int, for e.g. ID[154382] Out[58]: 'CN414149' How can I (without using loops) remove these type of occurrences so that I can use astype with peace of mind?
