Why i am getting TypeError: 'str' object is not callable, in reversed() function? [closed]-CodePudding

i am trying to write a program to reverse words of string at there places.

Example:-

str = "my name is xyz"

will become

"ym eman si zyx"

following is the program:-

str = "my name is atharva"
l = str.split()
print(l)
for var in l:
    print(var)
    temp_str = list(reversed(var))
    print(temp_str)
    list = ''.join(temp_str)
    print(list)

when i run the error i got the following error:-

['my', 'name', 'is', 'atharva']
my
['y', 'm']
ym
name
Traceback (most recent call last):
  File "<string>", line 29, in <module>
TypeError: 'str' object is not callable

Thanks in advanace.

Hope to here from you soon.

In the first iteration of your loop, this line assigns a string to list:

list = ''.join(temp_str)

On the next iteration you're trying to use list as the built-in function:

list(reversed(var))

But the built-in can no longer be accessed, since you replaced it with your string.

Don't use existing names like list (or str for that matter) for your variables. This destroys your access to their existing functionality

CodePudding user response：

You are running over build in function list

list = ''.join(temp_str)

rename your var:

str = "my name is atharva"
l = str.split()
print(l)
for var in l:
    print(var)
    temp_str = list(reversed(var))
    print(temp_str)
    str_list= ''.join(temp_str)
    print(str_list)

*Also this is a bad practice running over build in function str

CodePudding user response：

The reason is you are using the list as variable name and assigning it a str value which shouldn't be the case. Just rename the variable list to some other name. Also you can try out this code which is more optimized without using extra lists and all:

str = "my name is atharva"
l = str.split()
out = []
for var in l:
    out.append(var[::-1])
print (' '.join(out))

Output:

ym eman si avrahta

CodePudding user response：

You can change your code to what I have provided below:

txt = "my name is atharva"
reversed_list = []
print(txt)
for var in txt.split():
    reversed_list.append(var[::-1]) #This reverses the text

print(' '.join(reversed_list))

The output will be:

my name is atharva
ym eman si avrahta

I have change certain variable names too.
