代码:
l2=[]
with open("file.txt") as f:
data = f.read()
l1 = list(data.split('\n'))
for item in l1:
if item>=9000:
l2.append(item)
else:
item = item+9000
l2.append(item)
print(l2)
错误:
if item>=9000:
TypeError: '>=' not supported between instances of 'str' and 'int'
答案 0 :(得分:1)
由于item
位于文本文件中,因此它是一个字符串,您应该在比较之前将其转换为int
:
for item in l1:
if item.isdigit(): # if it is a number
item = int(item) # convert it to int
if item>=9000:
l2.append(item)
else:
item = item+9000
l2.append(item)
else: # not a number
# do something
