英文:
I need combine indexs of a tuple how can i do this
问题
我尝试将字母放大到单词的索引位置，但它不在相同的索引位置。
k = 'kars'
k = k[0].upper(), k1, k[2], k[3], k[4]
它在分布字母，如何将它们组合在一起？

Python有一个title()方法：
k = 'kars'
print(k.title())
# 或者
print(k[0].upper() + k[1:])
# 或者
def uppercaseAtIndex(k, i):
newK = list(k)
newK[i] = newK[i].upper()
return ''.join(newK)
print(uppercaseAtIndex(k, 1))
输出：
Kars
Kars
kArs
英文:
Python has a title() method:
k = 'kars'
print(k.title())
# OR
print(k[0].upper() + k[1:])
# OR
def uppercaseAtIndex(k, i):
newK = list(k)
newK[i] = newK[i].upper()
return ''.join(newK)
print(uppercaseAtIndex(k, 1))
Out:
Kars
Kars
kArs

''.join(letter.upper() if i == index else letter for i, letter in enumerate('thestring'))
英文:
Use a generator expression and enumerate to capitalize a specific index. Join the letters with str.join().
index = 1
''.join(letter.upper() if i==index else letter for i,letter in enumerate('thestring'))
