如果class UserCell: UITableViewCell {
override func layoutSubviews() {
super.layoutSubviews()
textLabel?.frame = CGRect(x: 0, y: 0, width: textLabel!.frame.width, height: textLabel!.frame.height)
textLabel?.backgroundColor = UIColor.red //only for demonstration
textLabel?.sizeToFit()
//detailtextlabel code
}
}
中的数字大于seqnum
,我试图删除第一位数字。
999
预期:
import re
filename = raw_input('Enter a filename:')
pattern = re.compile(r'SEQNO')
with open(filename) as f:
for line in f:
if pattern.search(line):
seqnum = line.split(' ')[1]
print seqnum
if seqnum > 999:
print seqnum[1:]
else:
print "Seq Number is not greater than 999"
输出:
Enter a filename:20181023.112225.11308.1.2
654
实际:
Seq Number is not greater than 999
输出:
54
答案 0 :(得分:1)
您需要将string
转换为int
。
替换此:
seqnum = line.split(' ')[1]
具有:
seqnum = int(line.split(' ')[1])
或者这个:
if seqnum > 999:
与此:
if int(seqnum) > 999:
因此:
with open(filename) as f:
for line in f:
if pattern.search(line):
seqnum = int(line.split(' ')[1])
print(seqnum)
if seqnum > 999:
print(seqnum[1:])
else:
print("Seq Number is not greater than 999")
编辑:
看起来很可能您正在使用Python 2.7,因为以下代码段可以在其中运行:
Python 2.7:
seqnum = "654"
if seqnum > 999:
print(seqnum[1:])
else:
print("Seq Number is not greater than 999")
输出:
54
相同的代码段,但是会在Python 3.x中引发错误:
Python 3.7:
Traceback (most recent call last):
File "main.py", line 3, in <module>
if seqnum > 999:
TypeError: '>' not supported between instances of 'str' and 'int'
