Question

https://www.sololearn.com/coach/64?ref=app

x = input()
z = ""
#1/6 test cases failed
for i in x:
if i.isdigit():
if i == "1":
x = x.replace(i, "one")
elif i == "2":
x = x.replace(i, "two")
elif i == "3":
x = x.replace(i, "three")
elif i == "4":
x = x.replace(i, "four")
elif i == "5":
x = x.replace(i, "five")
elif i == "6":
x = x.replace(i, "six")
elif i == "7":
x = x.replace(i, "seven")
elif i == "8":
x = x.replace(i, "eight")
elif i == "9":
x = x.replace(i, "nine")
elif i == "10":
x = x.replace(i, "ten")
elif i == "0":
x = x.replace(i, "zero")
print(x)

Answer 1

By replacing ones first before the tens, you have essentially turned tens into ones and zeroes.

Answer 2

Move i == "10" to the top of if statement. So that "10" will be checked from the string and replaced.

Answer 3

same

Answer 4

worked, thanks

for i in x:
if i.isdigit():
if i == "1":
n = x[x.index(i)+1]
if n.isdigit():
if n == "0":
x = x.replace(i, "ten")
x = x.replace(n, "")
else:
x = x.replace(i, "one")
