Can any explain me how end='' works here

Question

def rev_str(my_str):
length = len(my_str)
for i in range(1,length):
yield my_str[i]
# For loop to reverse the string
for char in rev_str("hello"):
print(char, end= '')
print()
# Output: olleh

Answer 1

The end='' is used to remove the default line break of the print function.
Example :
for i in range(4):
print(i)
Output :
0
1
2
3
And if you do :
print(i, end='')
Output :
0123
Hope this helps :))
