I'm a freshie. I would like to convert a numeric string into int from a sublist in Python. But not getting accurate results. 😔
countitem = 0
list_samp = [['1','2','blue'],['1','66','green'],['1','88','purple']]
for list in list_samp:
countitem =+1
for element in list:
convert_element = int(list_samp[countitem][0])
list_samp[countitem][1] = convert_element
You can do it like this:
list_samp = [['1','2','blue'],['1','66','green'],['1','88','purple']]
me = [[int(u) if u.isdecimal() else u for u in v] for v in list_samp]
print(me)
The correct way to do it:
list_samp = [['1','2','blue'],['1','66','green'],['1','88','purple']]
list_int = [[int(i) if i.isdecimal() else i for i in l] for l in list_samp]
print(list_int)
Let's go through the process step-by-step
countitem = 0
list_samp = [['1','2','blue'],['1','66','green'],['1','88','purple']]
#Let's traverse through the list
for list in list_samp: #gives each list
for i in range(len(list)): # get index of each element in sub list
if list[i].isnumeric(): # Check if all characters in the string is a number
list[i] = int(list[i]) # store the converted integer in the index i
[[int(i) if i.isdecimal() else i for i in l] for l in list_samp]elementanywhere inside it. Do you want to convert the first element to int or all elements that can be converted?
